Calvin Green

Director of rx training

My passion for helping people starts with a deep belief in the power of health and movement. Over the past 7+ years, I’ve worked with mothers, fathers, athletes, busy professionals, and individuals managing pain—guiding them toward real, lasting physical progress. I hold a Bachelor’s degree in Exercise Science and specialize in functional strength training, combining practical knowledge with a results-driven mindset.

After earning first place at the 2025 OCB New Jersey Natural Open in my debut bodybuilding competition, I’ve continued to coach others by sharing the lessons I’ve learned—adding my own unique twist along the way. Whether you're just getting started or ready to take things to the next level, we are prepared to help you succeed.

As director of training for Rx Training, I develop our small group personal training experience, workouts, and manage the coaching staff to provide the standard for strength training. Let's get to work.
