Jason Cooper

Certified Fitness Trainer

Jason (Coach J) has been certified as a personal trainer since the Summer of 2017, but has been studying in the fields of health and wellness since 2015. Also being certified as a massage therapist, Jason always tries to look at the bigger picture when it comes to his own own health and the health and progression of his clients. He understands that every individual client is going to have their own individual needs, so clients are never going to receive a cookie cutter approach with his programs. It is never about just lifting weights, it is never just about cardio, or just being the most flexible, however, it is about challenging yourself in a multitude of ways and discovering things about yourself that you once might not have believed to be possible. Therefore Jason uses an integrated training style in which resistance training, cardio endurance, balance and reactive training, core training, and flexibility and mobility are the focal points.

Jason’s Tip

“Don’t try to change everything at once (as it relates to your health). It is easy to want a big change all at once. Try focusing on one area of your health to start. Once you feel you have that momentum, then move on to another area of your health you would like to address.”

“Strength and flexibility go hand-in-hand. As you increase your strength, it is equally important to improve flexibility for optimal health and daily functioning. Yoga enhances physical training and promotes relaxation as well. It also brings calm and balance into your life!”
