Our Fitness Instructors:

Kyle O'DonnellKyle has been training for over 7 years now and weight loss and overall health are his focus and speciality. He grew up in South Florida near the beach where he actively played competitive sports such as baseball, basketball, beach volleyball and soccer. Kyle’s favorite part about training is watching his clients build confidence in themselves while reaching their fitness goals, and seeing the results carry over into their everyday life. The most enjoyable form of working out for him is hiking and anything outdoors. Staying active and working out is important to Kyle for an over all better wellbeing, but mostly so he can eat all the pizza he wants.
