Our Story

REX Fit was founded by physician Jay Feldman, DO. After years as a collegiate and professional Beach Volley player, he learned the value of motivation through community. In addition to his study of medicine and physiology as an osteopathic physician, Jay always kept a keen interest in personal wellness, nutrition, and functional exercise. REX is Jay’s vision of applying these values to a shared community while offering crowd-sourced wisdom and motivation, absolutely free of charge.

Community First

We are here to build a community of trainers and fitness enthusiasts who share the same love for motivation, and from that love encourage each other every step of the way. REX Fitness Club is the platform we use to interconnect fitness fanatics, and our REX Home Gym is an accessory to that free community.

We believe in the power of sharing what’s working for you; workouts, nutrition tips, supplement advice, and more. Helping you build an all-star reputation in our REX community while reinforcing you to take your own advice!
