Exercise Myths And Facts

MYTH Strenuous exercise outdoors is the best way to cleanse toxins out of your body.
FACT- Environmental Toxins (pollution) are a major consideration when you exercise outside. As your workout becomes more strenuous you breathe deeper and faster, this magnifies the negative effects of the toxins and increases your exposure.

MYTH – In the city, a sunny, windless day is sure to be low in toxic emissions.
FACT- Sunny afternoons without wind are actually the worst for toxic ozone emissions. The action of sunlight on nitrogen oxides and hydrocarbons from car emissions creates high concentrations of ozone. If you live in the city, it’s best to avoid strenuous outdoor exercise in these conditions.

MYTH – When you detox you should exercise heavily to clean out your body.
FACT- During a formal detox program, it is best to limit exercise while the body rejuvenates. Over exercising is to be avoided at all times, always balance exercise with recovery.

MYTH – It takes a large time commitment to develop strong muscles
FACT – It takes literally minutes. The body enhances it’s muscles because of a high effort, not long duration. Muscle cells experience damage. This happens as muscles lengthen under a heavy load. This stimulates the repair and growth process. It is quite similar to the way skin can be rejuvenated as a result of exfoliation.

MYTH – Building muscles is unimportant to overall health.
FACT – Building and maintaining muscles is essential to overall health. Muscles are our largest storage depot for glycogen. Glycogen is the way we store carbohydrates for use as energy. We are always confronted with the temptation of eating too many carbs. When we eat, especially starches and sweets, we require the hormone insulin to help us store these energy foods. Maintaining our sensitivity to the hormone insulin is imperative to good health. Increased muscle mass provides us with greater storage capacity, this means fewer carbs are converted to fat! Also, it has been shown as we become stronger, we spontaneously move more and therefore an upward spiral of health is created.

Jim Clarry is the CEO and co-founder of Persevera training studios in New York City. He has been in the trenches training clients, educating and mentoring other personal trainers and researching the latest science since 1988. His clientele includes Wall Street financiers, business leaders, celebrities, journalists, artists, athletes and other trainers.

Jim's journey to prominence in personal training began when he was in high school. Despite lacking the physical prowess of many of his peers, he diligently pursued his goal of performing at a high level in various competitive sports. He quickly found that the traditional training approaches that worked so well for the genetically gifted seemed to be ineffective for him. His obsession to break through barriers and unlock his own potential prompted him to develop a targeted approach to health, nutrition and fitness that he has continued to perfect over more than a quarter of a century.

Realizing that most successful people have average genetics and limited time - but also a competitive desire to look and feel their best - Jim tailored his protocols so that busy professionals could achieve exceptional results safely and without the unreasonable time commitment that so often derails health and fitness ambitions. Jim's passion is to help Persevera's members attain the physical and mental joy that he has achieved for himself. His revolutionary training system has inspired a passionate loyalty from his clients, many of whom have been training with him for over fifteen years.

Jim has been featured in Vogue, Men's Vogue, Self Magazine, New York Magazine and on Eyewitness News.


One of Jim's favorite weekly activities is taking the ice with his teenage son to skate through an hour of grueling hockey drills. Many of his friends and clients are looking forward to the day when he'll agree to branch out and take hip hop dance classes with his daughter. If that should ever come to pass, we'll do our best to videotape it for your viewing pleasure!
