Trimarni Coaching and Nutrition

After completing 17 Ironman distance triathlons, I have become good friends with fatigue. Over the past few years I have become much better at tolerating fatigue. Winning my age group at IM Chatt ('17), IMWI ('18) and IMLP ('21) and qualifying for the Ironman World Championship six times has proved to me that becoming a better long-distance triathlete is all about consistency, patience and strength.  Over the past few years, there's been a great amount of talk over fat burning as a metabolic approach to delay fatigue and to improve endurance performance. Carbohydrate fuels are limited in the body and glycogen (stored carbs) depletion is a major cause of fatigue during high duration activities. Therefore, by increasing the reliance on fat for fuel (because fat fuel supplies are unlimited in the body), endurance athletes can delay fatigue through increased fat burning. To increase fat oxidation during exercise, athletes often resort to fasted training, a high-fat/low carb...

Picture source Body positivity challenges the ways in which our society presents, celebrates and views bodies.  Sadly, far too many body shapes and types have been shunned by the mainstream media or not classified as beautiful. Our society has a fixation on the "tiny" ideal and encourages everyone to fit the social standards of being lean. This is why there are so many movements promoting body positivity. Because many people feel discriminated against because their body doesn't meet the "ideal" image, the body positive movement challenges social norms and promotes the belief that all bodies - regardless of size, shape, gender, physical abilities or skin tone - should be accepted. The body positivity movement is a necessary movement but it can also be controversial - can you have a positive relationship with your body and desire weight loss/a change in your body composition?  First off, it is a myth that large bodies are unhealthy. Being bigger doesn't mean b...

Height, hair color, eye color, skin color. We can't control or determine these things when we are born. Yet we are taught that we can (and should) force our bodies to achieve a specific shape, weight, size and appearance. We are fed information that our weight matters, even if it comes at a cost of our mental and physical health. But not all bodies are set to be at a specific body composition. Every human has a specific weight range for their body to function optimally. If you've forgotten or failed to learn the importance of maintaining a healthy weight, you may be familiar with the difficulty and frustration of restricting food in an effort to change your body composition. Trying to achieve or maintain a body composition that goes below your body's set point often by restricting energy or over-exercising impairs the functioning of your body. No matter how hard you fight, your body will fight back to stay within a range where your body operates and functions optimally. The...

  In our weight and image-obsessed society, it can be difficult to maintain a healthy relationship with food and the body when you are having an "uncomfortable body" day. Our culture is really tough on bodies - we are taught that our current size/shape/weight is a problem and it requires immediate fixing. The human body is amazing. It’s constantly working for you. As you go through life, it’s only natural and normal that your body will change along with you. The body is complex and dynamic. Every day your body is adjusting to its environment and the stress placed on it. Let's look at some of the incredible ways that the body works for  you and why you shouldn't overhaul your diet or exercise regime if you feel or see your body making a small shift in size, shape or weight throughout the day.

Within certain sports (ex. triathlon, running, cycling, etc.) it’s not uncommon for athletes to manipulate the diet in order to achieve a lower body fat percentage - believing that a body that weighs less will lead to athletic success. Whether for aesthetics, competitive leanness, body dissatisfaction, or in pursuit of an ideal “race weight,” what may start as an innocent attempt to lean-up or to lose a few pounds, can easily spiral out of control - undermining health, training, recovery, performance and mental well-being. Although there are safe and healthy ways to change body composition, it’s not uncommon for athletes to engage in unhealthy weight loss methods, resulting in great emotional and physical consequences. Disordered eating is a general term describing harmful, obsessive or extreme eating behaviors that are used in attempt to achieve a lower than normal body weight. Examples include rigid or righteous eating, fasting, anxiety, control or preoccupation with certain foo...

Several weeks ago I was contacted via email by someone from a company who asked if I was interested in receiving a complimentary  DEXA Scan  (along with Karel) in return of a review. As you may know, I am not a fan of the scale and I never weigh myself. Considering all that makes up your body, your body weight can’t accurately be told by a number on the bathroom or BMI scale. But this doesn't stop far too many athletes from daily or weekly scale weighing - often feeling like the scale runs or ruins the day. A DEXA Scan is a reliable, gold-standard way to precisely measure body composition (I discussed this in my book Essential Sports Nutrition ). DEXA stands for dual energy x-ray absorptiometry.  More than just a weight, a DEXA Scan tells you what you are made up of - muscle, fat and bone. You can see muscle asymmetry, visceral fat and bone density. For the athlete with excessive body fat, weight loss may improve health and sport performance. However to pressure f...

We all come in different sizes and shapes based on our unique genetic make-up. However, it’s common to turn to exercise to change the way that you look. Some athletes may desire a body composition change to help improve endurance, speed, strength, power and agility. Others may want to improve health. While health and performance may be of interest, athletes are often heavily invested in appearance - wanting to look leaner or more like the idealized image of an athlete in their sport. Keeping in mind that athletic success cannot be predicted based solely on body weight and composition, athletes come in vastly different body compositions. Because no two athletes are alike and sports invite athletes of all different sizes and builds, your body weight should not be your sole focus for sport enjoyment.  Due to pressure from society and coaches, it’s not uncommon for many athletes to have body image struggles, despite not being overweight or over fat. In turn, many athletes resort ...

Many athletes believe that a change in body composition will improve speed, power, fitness and performance. Whereas some athletes are genetically made with a body composition that is suited for a specific sport, most athletes put a lot of work into trying to reach a body composition goal. This leads me to the point of this blog post...athletic success requires work but how much work is too much work? Should athletes have to "work" on changing body composition on top of the training that is required to physically prepare for an event?  This is why I caution athletes to be careful how they go about body composition changes. The body should change naturally as a result of a solid foundation of eating, nutrient timing and proper use of sport nutrition products. It's also important to make sure your idea of how you think your body should look isn't based on the idealized image seen in media - one that emphasizes little to no body fat and extreme leanness and/or musc...

Nearing the 2-3 months out from a key race, many athletes start paying close attention to any limiters that could potentially sabotage race day performance. Weight is typically one of those "potential" limiters that comes to the front of the mind for my athletes. Although weight can play a positive or negative role in performance, it's not the only way to improve or destroy performance. Sadly, when athletes start looking at performance and how to get faster, stronger or go longer, weight becomes the only focus. It's not uncommon for the athlete who wants to achieve a specific body composition to look for strategies and behaviors that are extreme in order to make for quick changes. Because most people won't keep up with new habits if they don't result in quick changes or feedback, many of the strategies that athletes take to change body composition adversely affect health. Fasted training, restricting fluids and calories during prolonged sessions, not focus...

A change in your body composition to ensure a performance improvement ( race weight) should be the  outcome  of a well planned and executed fueling and training plan, alongside a healthy and balanced, non-restrictive daily diet. Just because you lose weight or achieve a certain body fat percentage, this doesn't mean that you are physically, mentally, emotionally and nutritionally prepared to perform well on race day. You may "look" a certain way but this doesn't mean you will preform a certain way. When a healthy change in body composition is desired, it should not involve restriction, elimination and obsessive strategies. While some sports may reward a "leaner" build, this doesn't mean that you can't be successful in your sport with a little more cushion with your strong bones. As it relates to the sport of endurance triathlon, you are not penalized if you are carrying around a little more body fat on your frame for a strong body can better tole...

Changing one's body composition will only offer a performance advantage, however, if we first establish the goals and methods uniquely suited to each athlete's individual needs. Numerous so-called "magic bullets" circulate in the health and fitness world for losing fat; triathletes should be cautious of "strategies" that promote quick results. These methods pose a great risk for losing lean tissue, bone mass, and gaining body fat, lingering fatigue, illness, injury, compromised recovery, and ultimately, performance decline. Perhaps even worse, a reckless weight reduction program can trigger disordered eating habits, paving the way to a dangerous eating disorder. Although a certain perceived "leanness" may in fact be athletically advantageous, every athlete has an ideal body composition range where he or she will feel, function, and perform the best. It cannot be overstressed that the bathroom scale provides irrelevant information about you...

Picture source Are you counting down the weeks until your first triathlon race of the upcoming season? I am itching to race!! As it relates to athletic performance, changing body composition will only offer a performance advantage if goals and methods are appropriately established. With many attractive approaches for fat loss, triathletes should be cautious of weight loss strategies that promote quick results as there is great risk for losing lean tissue, bone mass or gaining body fat, lingering fatigue, illness, injury, compromised recovery and performance decline.  Additionally, a weight reduction program may trigger disordered eating habits, paving the way to an eating disorder.  Typically, low energy availability occurs when athletes consumes less than 30 calories per kilogram of fat free mass per day. For women to stay in good metabolic and hormonal health, this number is typically around 45 calories per kg of fat free mass per day. I'd like to think that...

As an athlete, you probably feel that you work very hard to develop the necessary skills, resilience, stamina, power, speed and endurance to help you prepare for your upcoming athletic events. Developing the fitness to participate in a running or triathlon event requires a lot of training and it takes commitment and requires patience, so it's assumed that skipping workouts, being "all in" all the time, not caring, deviating from your training plan to do what other athletes are doing, or haphazardly guessing your way through training are not effective ways to reach your race day goals. You simply become inconsistent with training, you lose confidence in what you are doing and you may compromise your health. Is nutrition an important component of your training? If you don't work at healthy eating, you miss out on one of the best opportunities to improve your performance and to keep your body in good health. To perform at your best, your body needs to function at it...

Source Athletes are constantly being told to lose weight. Whether it's directly from a coach or from the messages and images viewed on social media and in articles and on TV, we live in a body obsessed society. With so many different body types and so many different styles of eating (aka "diets"), driven by misconceptions about food, body dissatisfaction and misguided strategies for eating "right", it doesn't surprise me when I see the health and performance of competitive, body conscious, goal oriented and driven athletes, deteriorate. Most athletes have no idea how much energy is needed by the body to perform at a high level. Most athletes do not feel they deserve to eat "that much food". Now more than ever, most athletes are very obsessed with how much they weigh. Due to so many false statements relating to body weight and performance, athletes are constantly trying to be thinner, leaner and lighter, while trying to get faster and to go ...
