Since the age of 5 I have been competing in sports, it has always been a passion of mine. Competing in 4 sports in HS (Football, Track, Wrestling, Baseball) I didn’t touch a weight until my sophomore year as I was smaller than most of my teammates and was strongly advised by my coaches to put on some weight and size.

Hi, I’m Maran Subramain, and I believe in respecting the uniqueness of each individual. My philosophy in life is, accept who we are, appreciate what we have, and improve where we can. Valuing a healthy lifestyle and my professional research interest in health and nutrition have motivated me to get certified as a personal trainer. A certification from the American Council on Exercise has allowed me to gain in depth knowledge in fitness and coaching, and gives the opportunity share my passion in holistic health focusing on both mind and body strengthening.
