In Person Training VS Online Training

well HELLLLOOOOO there!

It has been forever since I’ve shared a post with you, and I apologize, but I’ve been a little bit BUSY.

Once you’re all caught up on that, you’ll be happy to know that living the majority of my life in a gym has really helped to inspire what I hope will be incredibly helpful posts.

So let’s dig in to today’s post and hash out the benefits of different types of training.

One of the biggest issues facing training today is that it has been cheapened by its own. Trainers who deal under the table and use fitness facilities without expecting to pay has driven facility pricing up and the professionalism of training down. This is a pattern that professionals like myself are trying to fight.

So, how do you know if you’re getting a GOOD personal trainer?

Well, for starters I would recommend being a bit more picky when choosing your personal trainer.

Think of your personal trainer as a part of your medical team. Would you go to just any old doctor off the street? Your trainer should be chosen with care.

Once you have established how to pick a trainer, the question may then be if you should hire an in-house trainer at your local gym or an online trainer. And here is where it can be tricky….

Training is not regulated. Anybody can open an online training business and call themselves a personal trainer (or worse, a celebrity trainer).

One BIG upside to hiring an in-house trainer is that most gyms require a national certification and they make sure trainers keep up with continuing education credits.

So, when you looked in to that online trainer who charges over $100 a month, did you research their credentials? Do your homework and keep yourself protected.

Another issue with training is what I believe to be the BIGGEST thing an in-person trainer can help with: FORM.

A hands on trainer can help make minute adjustments that lead to better muscle recruitment which will in turn help you reach your goal faster. These adjustments need to be made in person, cause I don’t care how awesome you think you are, Skype won’t cut it when you need to truly make adjustments. Hands on adjustments make all the difference in the world AND help to prevent injury.

In house trainers can also help you to track progress more effectively. PLUS, if you struggle with getting workouts in, an in-house trainer is a great way to set up that habit. My clients are given homework to complete each week and I ask them to check in with me at the gym, even if they don’t have an appointment that day. This ramps up the accountability factor we all need.

Are all trainers created equal?

Absolutely not!

I am blessed with a staff of trainers who are willing to continue to learn. A lot of trainers are only willing to go as far as the money. A good trainer will give you more than you paid for. A great trainer will depend on science to blow theory out of the water and help you reach your goals faster than you thought possible.

So, how do you pick a trainer?

Do your research.

If a trainer is dealing underhanded and unwilling to pay a gym to train there, they won’t be fully committed to you either. An online trainer should be researched just as carefully and make sure you’re not simply looking at pictures……you can get those anywhere.

Seek out referrals for a good trainer in your area OR check out for a listing.

Is training cheap?

I wouldn’t trust it if it were. Good training will encompass the entire lifestyle, so it should take a chunk of time out of the trainers schedule. Consider this when looking at trainers. Also consider the fact that the better and more experienced the trainer, the more expensive they will be.

When it comes down to the nitty-gritty for training, you are paying for far more than that 1 hour session. If you’re lucky enough to get a trainer/nutritionist combo, then you should be getting plenty of nutrition education along with strength training, exercise sequencing, cardio workouts, flexibility training and core work (every day with me is core work). This is why training should be considered an investment. If your trainer doesn’t take your investment seriously, find another trainer.

Training is a great way to get results, stay injury free and develop a love for fitness…..IF you find the right fit.

Simple Sips: Hydrating Techniques for Youth Athletes

Yes, I’m going to talk about water again :) WAIT! All the info will help, even if you don’t fall into the youth category. Besides, it’s a way to look busy at work so read on!

If you are the proud owner of a young athlete then you should know one important detail (other than the fact that your own life will need to take a back seat while those in your back seat get carted around like Ms Daisy)…adolescents dehydrate much faster than adults AND the signs are not as readily noticeable. The reasons? Well, dehydration occurs faster in those between the ages of 6-14 due to the fact that their bodies are still in need of more water for the growing of bones, sinews, ligaments, etc. More water is already being used for that pesky growing process, so the muscles and surrounding tissue don’t hold as much. This means that as your athlete plays their heart out, they are dehydrating at an accelerated rate. So, why don’t the symptoms show up? Well, technically they probably do, it’s just that most don’t notice them. The symptoms of dehydration can include the following:

  • Dry mouth
  • Headache
  • Nausea
  • Stomach cramps
  • Muscle cramps
  • Fatigue
  • Dizziness
  • Achy muscles all over
  • Trouble collecting ones thoughts
  • Feeling thirsty (I know that’s a DUH, but by the time we feel thirsty we’re in the danger zone)
  • Slow in perspiration, no matter the temp
  • Slow in hand/eye coordination

Now, these don’t generally all hit at once and when your kid is playing for the win they tend not to notice a little cramp here or a dry mouth there. It’s not that the symptoms aren’t there, it’s that they have better things to think about. Your job is to focus on preventing dehydration altogether as opposed to simply trying to spot the symptoms. Once we reach the point of nausea, muscle cramps, slow perspiration and cotton mouth, chugging a liter will do no good. As a matter of fact, rapid water consumption at this state will more than most likely end in the water running for the nearest exit….meaning a barf bomb for your kid.

In order to prevent dehydration in young athletes, we need to plan ahead. For starters, don’t feed your kid crap on a training day! I see this over and over on the football field: a kid has a couple of hot dogs for lunch and washes them down with a soda…THAT is the one who passes out on the field. They end up starting a grueling 2 hour practice already dehydrated (food for thought: carbonated beverages pull water from your bones….yeah) and then end up on the ground or in the hospital. Use your parent brain and take care of them. Make sure they drink water throughout the day (that’s why schools have those fancy fountains!) and if practice or the game lasts more than 45 minutes OR is in extreme heat, consider sending a sports drink with your kid. Since sugar is the enemy of hydration, I opt for G2 or other low sugar drink. You can also water it down a bit as needed. The sodium and potassium help the body to hold onto water so as not to dehydrate during a game/practice session. I also really like the Gatorade chews. They have some that are simply for hydration and easy to carry in one’s pocket as well as some pre-game carbohydrate chews that help the body stay fueled without pulling from its own muscle. Head to the game with water in hand and place it on the sidelines for your kid (nobody wants their mommy running water out to them people!) and make sure to have a hydrating beverage in the car when you pick them up from practice.

Snacks can help with hydration as well. Vegetables are water dense and can provide a whopping 30% of our daily water IF we eat enough. I always send my son brocoli, carrots, cauliflower, cucumbers, tomatoes, etc. at lunch, especially on game pr practice days. If your kids are more used to burgers and fries, offer them the knowledge on what it takes to become a better athlete. Example: world-class athletes don’t chow down on a double meat and fries before a game…. Train your gut and your butt and you’ll reap the benefits on the field or the court, simple as that. Ask your kid to try it for 2 weeks and see how they feel. My son noticed a large difference in how he felt when he took a homemade lunch and when he bought the processed junk at school. He now asks that I make his lunch and often times throws in some help as well. And he’s in highschool now :)

Limit seriously salty snacks before games, but don’t take salt out of your athletes diet! Athletes need more salt. That’s reason to become an athlete for some people… Keep the diet varied and spend just a little extra time getting prepped for games. Pack a cooler with healthy snacks, including LOADS of fruits as these provide hydration and quick energy. Think you’re too busy? Tell that to the doc who has to stick a huge needle in your dehydrated kids arm. Yeah, you can pull time. In today’s world most grocery stores have fruits, veggies and even recovery drinks already made and within close proximity to each other. Invest in refillable bottles and for goodness sake, make your athlete help in this process! Life isn’t a one man show, but a big production where we all have a part to play :)

Stay hydrated and stay healthy!




Youth Athletes: Sports Nutrition and Training

Happy Monday!

I’m getting back into the swing of things since the Summer is winding down (sad, but so true). Today, I’m going to start off August with info on Youth Athletes. Your kid (if you have contact with ANY young athletes, this will help you!) can benefit greatly from proper knowledge on training and nutrition as the sports seasons start to come into full swing. Some youth prefer seasonal sports such as football and basketball, while others can play soccer or baseball seemingly year round. If you know youth (I’ll be working mainly with ages 8-17 here) then the knowledge you will gain during this month will prove priceless in keeping them on top of their game and injury free. Let’s get started!

Parents and Caregivers:It’s NOT about you…

Harsh start, I know. Here’s the real deal though: your kids chosen sport has nothing to do with you. If they chose baseball because it was your idea and your hopes are hung on them going farther than you did and reliving your glory days….it will end badly. Usually resulting in pushing too far which can ultimately lead to life long injury. Our jobs as parents and caregivers are to encourage them and help them along their own path…not relive our own.

Nutrition is PARAMOUNT during the training season.

Developing solid nutritional habits is the most important step you can take during training. They can run faster than anybody on the planet, but poor nutrition will outrun even the fastest kid. This can be difficult to understand as most people equate nutrition with weight. Nutrition is way bigger than weight, it’s about preventing injury and creating an environment in which the body can fully thrive. For example: a water loss of 10% (this is before the thirsty feeling kicks in) can cause delayed reaction times and dizziness. This means that if your athlete starts the game slightly dehydrated they have a higher chance of injury due to overcompensation. Too few carbs in the diet can lead to the body pulling from muscle during a training session or game. When the body begins to eat its own muscle, we experience painful cramps that can slow us completely. The body hits survival mode and your kids could be the one hitting the grass in severe pain. Poor refueling after training or games will result in muscle loss and encourage more catabolic behaviour within the body. The result? Your athlete will slowly begin to think that they aren’t “meant” for the sport…refuel properly and they have the best chance for keeping the muscle their body is trying to establish and raising the bar on the game itself. All because you rock as a parent :)

Consider hiring a professional.

PROFESSIONAL is the key term here. Interview the person that may be working with your athlete. Don’t assume they are qualified just because they work at a gym or for a sports facility. I know a lot of completely unqualified people who work in those arenas. It’s a simple question: are you certified to work with youth athletes? Follow up to a yes: May I see that certification? Aside from that, feel free to ask for records of CPR certification, insurance and any other specialties. I believe in making it a point to ensure you are hiring somebody who knows what they are doing, especially when it comes to your kids.

Educate your athlete.

The number one thing I have learned in working with young athletes is that mom and dad can’t just fall back on the Nike slogan JUST DO IT. Kids are ripe for planting knowledge. Explain to them WHY they need to drink their water. Explain the benefits of potassium and sodium in the diet. Explain why that double meat fast “food” burger isn’t nearly good enough to refuel after training. Size your response to questions based on your athletes age. My kids started learning about nutrition very young and now, they get it. They understand why they need to pay attention to their bodies and they dig the fact that we don’t do fast “food”. Why? Because it’s NOT food! It’s processed junk and the body would rather not use it to fuel muscle, so it gets stored. We have burgers…but they’re the really good ones :)

Every week I’ll bring you a recipe for pre-training/pre-game. This week:

Protein and Carb Pancakes

Both of my young athletes (and myself!) LOVE these things. They are the proper ratio of proteins to carbs (60/30) with just a tiny bit of fat (10) since you don’t want to train or play on a fatty stomach. Serve these 30-60 minutes prior to training/gaming and your athlete will be ahead of the pack already.


2 whole eggs + 4 egg whites

1/2 cup quick cooking oats

2 tablespoons unbleached all-purpose flour (you can use gluten-free if needed)

cinnamon, ginger, nutmeg, etc for spice

OPTIONAL: 1 scoop whey protein, flavor of choice (I only recommend if your athlete is over 10 years old and pretty active)

milk of choice until consistency meets how your kids digs their pancakes (my kids like them pretty thick)

Mix together and cook in pan or on griddle until slightly golden brown.

Top with fruit (bananas rock!), natural honey or natural maple syrup.

The natural sugars will help with energy, but don’t overdo as too much sugar can upset the GI tract during vigorous activity.



Come back all month for more on keeping your athlete on the top of their game!


This One’s for the Parents

At the risk of being a fire starter (who am I kidding? I love to start fires), I feel the need to address a growing problem that is making itself painfully evident.

If you are the parent of a youth involved in any sport, it is YOUR responsibility to make sure your athlete is properly fueled for practices and games!!!!!!!!!!!

I wish I could just assume that line is sufficient, but I have witnessed nutrition deficiencies that tell me we still don’t get it…..

Younger athletes are different from weekend warriors and gym rats. Children, age 5-16, who participate in sports need to be properly fueled. This means that they need plenty of water, not a Route 44 of choice from Sonic people! Corn chips, french fries and handy wrapped sweets are not considered fuel either. End of story. Youth are more prone to dehydration and improper fuel utilization especially if they are not sent out on the field, or court, with the advantage of proper nutrition. It’s really not that hard, but it’s something most parents simply don’t think about.

I was helping to coach my daughter’s soccer team last night. Practice is from 5-6 p.m. and her team is girls from 5th-6th grade. Most of the girls showed up sleepy and lacking energy, a sure sign of dehydration. Several made comments that they were hungry. Do you know what happens when you work out in a state of dehydration and hunger? Catabolism. It’s about as much fun as it sounds. The body, in its search for energy, will slowly start to shut down essential organs, such as the liver and digestive system (hello stomach pain while running!), and pull from the nearest source: muscles. Sending your child to practice without proper hydration and fuel means that their body will turn and begin to break down its own muscle tissue, essentially eating itself. How’s that for love? Not too good.

I get that we are ALL busy. I’m working from the time I wake until I hit the pillow and I’m usually driving between classes and clients, but I assure you my athletes are always well prepared. How can you fuel your athlete and ensure that they are safe and well hydrated for practice and games? Here are a few of my tricks:

  • Send water for lunch or make sure they drink water at home. Schools offer fountains, but it’s rare that kids (especially junior high and high school) have the time to get in enough water. Pack a bottle of water and encourage your youth to drink it at lunch. “But they don’t like water”. This is a fight you need to pick. Don’t be a wimpy parent and then have to explain to your child that the reason why they passed out on the field and now have to be hospitalized is because you didn’t want to utilize your parental rights. Drink water.
  • Make sure they have water AND an electrolyte beverage for long practices and games. Both my kids always have a bottle of water for during games and one for after. You can also send a G2 or Powerade (low sugar) mixed with water. These are particularly important if it’s extremely hot or they have to wear a lot of equipment (i.e. football pads).
  • Make sure they have some pre-game/practice fuel. You don’t want them practicing on a full stomach, so these are things that are easy to stuff and store. A handful of almonds and an apple, a banana and a piece of toast, some granola and apple juice or even a low sugar protein smoothie (if you have time to make it). If you pick your athlete up and head to practice directly following work, consider planning ahead and packing the snack(s) in a cooler for later. It should take less than 2 minutes and the payoff is phenomenal.
  • Provide healthy snacks for the team. When we’re in charge of snacks we always bring water, bananas and oranges (since post-game is the best time to get natural sugars in to replenish the muscle glycogen that will store from the meal that follows), pretzels or trail mix and maybe a little dark chocolate as a treat. Mounds of processed foods will do nothing but make athletes cranky and sleepy. Skip the Cheezits and head for the produce.
  • Make sure they have a good meal following the practice/game. It doesn’t have to be a 4 course meal. Just make sure they get proteins and carbs to rebuild the muscle. Spaghetti and meat sauce, chicken with rice and veggies, potatoes with chicken and salad, etc. are all great options and easy to make before hand.
  • Keep the items you need on hand. I buy protein bars for my son since he does a lot of after school athletics. I simply send them in his lunch OR he can throw them in his binder.
  • In special situations I do use electrolyte and/or carbohydrate blocks. You can find these at the local sporting goods store or health food store. These blocks contain electrolytes and often fast digesting carbs. They are small and easy to digest, BUT you have to drink plenty of water. Since the schools love to believe it’s totally fine to deprive children of water and fuel, I make sure my son has these tucked away for pre-game/practice. They are small enough to have in his pocket and something he can chew up while dressing out.

The bottom line here is don’t depend on somebody else to fuel your kid. If we would just commit to up the water and lower the sugar, we may wake up to different kids as both dehydration and excessive sugar can contribute to changes in personality and temperance. Fuel your athlete for success and you won’t regret the small amount of extra time you have to spend. Take the accountability and make sure you explain this to your children. This way they can have a say in the healthy snacks which can lead to better adherence. It’s never too early to start living healthy!




Nutrition for the Next Generation


So, as we move into the weekend, what comes to mind? Is your weekend full of adventure and fun? Or is it the more mundane tasks that await?

If you find yourself in the latter end, no worries! You can take the opportunities given to make sure you get some extra, fun movement into your everyday lifestyle.

  1. Choose to start the day out right! I am well aware that not everybody appreciates the early morning weekend hours like I do :) , but you can choose to get your fit on before breakfast. Check out the fitness page on for FREE workout vids. Most of which are about 10 minutes long. You can pick anything, from Pilates and dance, to kickboxing and weight lifting. It doesn’t have to last an hour to brighten your mood.
  2. Plan your meals/snacks in advance. This time of year a lot of us are headed to the ball park to watch the kids play. Don’t succumb to ball park food! It’s not just the calories, but this type of food is highly processed and the more you ingest throughout your lifetime (how many years have your kids been playing ball?) the slower your metabolism will be.
  3. While at the park, get OFF the bleachers and stop being the bench warmer in life. Yeah, I said it…. You can cheer your little ones even better while standing and moving, keeping your blood flowing, oxygenating your brain for better function, and showing that you really are involved!
  4. I know you need to clean the house (as most of us do!) so split up the chores and make it a game. Got young ones? Make them honorary detectives and send them on a “hunt” for items that need to be put up. Then, end the housecleaning with a walk. If a local ice cream parlor ends up on your walk, well then it was meant to be! :)
  5. Plan a little park time. Take the kids to the park and challenge them to chin ups on the monkey bars. By the way, totally cool if you “let” your kids win! Run around the park with them, or walk through the glorious nature around.
  6. Lounging by the pool? Not if you’re fit! Laying out is detrimental to your skin (SPF ALWAYS!) and your waistline, so get moving. Swimming is good, water volleyball is even better. Challenge others to a game, or see which one of your kids can out do you on laps. Make it fun and make it count!

No matter what the weekend has in store, it’s up to you to become an active participant in your life. So get moving and find the FUN!


P.S. I’ll be trying out paintball for the very first time this weekend. I’ll let you how it goes!

Fitness FUN!

OK, so this is one of the MOST fun ways to get your whole family involved in fitness. No worries if it’s just you :) it can still be fun AND very effective. For this workout you will need a deck of playing cards and some space to move :)


Each Face card has a move attached to it, while the numbered cards will tell you the reps. Approach this workout with an open mind!

King of Hearts: Push UP

Queen of Hearts: Squat

Jack of Hearts: Crunches

King os Spades: Sumo squat

Queen of Spades: Alternating Front Lunge

Jack of Spades: Triceps Dips

King of Clovers: Bicycle Crunches

Queen of Clovers: Alternating Back Lunges

Jack of Clovers: Alternating arm/leg reach (Quadruped Reach)

King of Diamonds: Jump Squats

Queen of Diamonds: Walk Outs with Push Up

Jack of Diamonds: Jumping Jacks

Every ACE is 1 minute of running :)

So, divide the cards up by face cards and aces in one deck and the numbered cards in another. For beginners and young children, you simply pull one card from the faces and do the numbered card as repetitions.

For example, if you pull the King of Hearts (push ups) and the 8 then you would do 8 push ups. You can allow the kids to pull from the decks so they feel more involved. Move quickly to increase the intensity. To make it more challenging you can pull 2 cards from the number deck and add or multiply to increase reps. For example, the King of Hearts (push ups) and a 2 and 10 would be 20 push ups (or you can simply add to lower reps).

Have fun with it and challenge yourself! Think outside the box a bit and if you’re willing, let the kids come up with moves for the face cards. The sky is the limit and the fun is fantastic!

To the Fit Life!


Nutrition Essentials

When it comes to feeding your family, there are some essentials to keep on hand and in mind so that everybody stays healthy:)

  • Wash and chop vegetables beforehand so they are readily available. Most grocers offer already prepped veggies too. Place them in baggies or reusable containers at eye level in the fridge. That way, when a snack attack hits, you’re ready.
  • Wash fruits and place them beside the sink. I have a fruit bowl beside my sink and keep it stocked with oranges, bananas and apples. Berries get washed and placed in the fridge. Watermelon and other melons are portioned out into containers and placed in a prominent place. That way when we get hot from playing we can easily get some healthy fuel.
  • Add some flavor. Both of my kids take veggies and a fruit to school every day. The veg is in a baggie and I always put a lemon and lime slice with them. The kids LOVE this as they can squeeze the slices over the veg to give it a better, more refreshing flavor.
  • Make your lean proteins in advance. I grill/broil chicken breasts, slice them, then place them in containers. This way I have them on hand for quick grab-n-go lunches and also ready to go dinners.
  • Keep plenty of frozen veggies on hand as well. This way you’re 5 minutes away from adding vegetables to your dinner. Nix the butter laden ones and go for fresh. Place them in a small pot with some chicken stock and play around with fresh herbs to season them. We really love fresh rosemary and parsley with our mixed veg.
  • Keep high fiber, whole grain crackers and breads on hand in the pantry. These help to fill you up and give you energy too.

Should you choose to keep treats in the house, go for some that have at least SOME nutritional value: dark chocolate, dark chocolate covered almonds, dried fruits, granola bars, protein bars, etc. keep these in a container in the pantry. i use a large white bin and keep it above eye level. That way these treats are there when we really want them, but we are less likely to eat them first.

Keep in mind that staying healthy is not as difficult as most think it is. With a small amount of planning and some dedication it is the easiest part of your day!

Stay healthy!



How to feed your youth

One of the biggest debates that resides in the minds of parents and caregivers usually has to do with the nutrition of those in their care. I mean, it stands to reason right? We spend a lot of our time feeding ourselves and our loved ones. With childhood obesity on the rise, nutrition is honestly the forefront of winning this ever-growing battle. As parents and caregivers we have the ability to set our children up for a lifetime of good health OR a lifetime of poor health. The choice is all ours.

So, let’s start with the basics. The first fact is that we buy the food in the house. I mean, I don’t send my 10-year-old to the store alone to pick up that weeks groceries. So, the first thing is to make sure that you are involved in planning the food for the week. Think ahead, just like you would if you’re planning a big road trip. Make sure that you have PLENTY of healthy snacks on hand at all times. Fresh fruits and vegetables are very appealing to young taste buds IF they are already washed and ready to go. I wash my fruits and veg after the store trip, then chop them up and put them into small containers. These containers are then placed in a prominent place in the fridge: EYE LEVEL. Yes, I know there are several drawers for this purpose, but when was the last time you dug into the drawer as opposed to hitting the chips in the pantry? Yeah, EYE LEVEL. The bright colors and freshness of the produce has been shown to create an immediately favorable response. That means if it’s available and ready to eat, kids will reach for it!

Another tip is to limit the amount of processed junk that is allowed to hang out in the house. It doesn’t mean that chips will never again cross the threshold of your kitchen, BUT it does mean that in the fight to better health, these foods are limited and no longer deserve permanent residence in your bread box. You and child deserve better food and better health, simple as that. So the chips, cookies and candies are bought only on special occasions. This will begin to treat the emotional dependency on food for comfort.

Potions are usually out of control for most of us. I know I can put away MASSIVE amounts of food if left to my own devices! When in doubt, use your hands as your guide. Protein will fit in the center palm, veggies take up 2 handfuls, grains are a closed fist, and fats are the tip of both thumbs. This holds true for your kids as well. Far too often we as parents give our children the same amount we eat and sometimes even more. We over feed to show love (totally different post!) and this causes a world of health issues. Stay within your childs portions and when they aren’t hungry, don’t force them to eat it all. In our home, we simply put leftover food away and if my daughter pops up “starving” an hour later, we reheat. Most times kids just may not be hungry at the time. If your child is chronically not hungry, look at the amount of snacks being eaten as well as the amount of movement between meals. Ever notice how little Timmy is famished when he gets home from school, but after a snack and some TV he’s not interested in a healthy dinner?

Last, don’t put your child on a “diet” of any kind. Children need to focus on the nutrients they get (adults too, but again: different post) and by placing children on any type of diet, we cut out essential nutrients that they need to grow. This will affect growth of healthy tissue as well as brain function. So, let the focus be on gaining more access to better nutrition and they will be set for life :)

Be sure to check back tomorrow for a fun family game that incorporates fitness into game night!

In good health,

How to Strengthen the Back

Yes, I know it’s youth month and that’s what I’m helping you with! Recent studies support that children as young as preschool can and should participate in some for of resistance training. The video above will actually be MOST helpful for those whose children/youth are involved in sports. By strengthening the back muscles you allow for better postural alignment and better core engagement which will result in an increase in power. This is particularly helpful for children in sports such as baseball, basketball, football, track and field, tennis, swimming, etc. A strong back equals a strong athlete.

This workout is cool for those 12 and over :)

Do 3 sets at 12-15 reps per set
