Subversus Fitness is located in the heart of Center City, Philadelphia at 1229 Chestnut St, and is the home of CrossFit Center City, an affiliate since 2009 as well as coaching Olympic Weightlifting and Powerlifting through the Liberty Barbell Club to both the seasoned athlete or the eager beginner.

Fitness is effective when it reflects what you need, not any one prescription, movement or style. We take a long-term approach to the development of you as an athlete. We start that with a discussion of your goals, experience, and overall health.

Next, we build a custom training plan for you utilizing our different programs.

You can't start with a more comprehensive, yet adaptable program than this for your athletic journey. Using this unique approach, members can progress at a pace that is appropriate, yet challenging and personally satisfying into the full scope of Subversus Fitness resources and programming. Enroll on your schedule! Get stronger and healthier with our individualized approach to a stronger you.

Frequently Asked Questions

Why can't I jump directly into your full schedule?

We care about your long-term safety, not just today’s workout. Our priority is developing your full athletic potential and that requires a plan that reflects your body. Our one-on-one On-Ramp Program lets us safely and effectively teach you the ins and outs of our programs, as well as giving you the space to learn with a coach’s full focus on YOU. All of our programs and workouts are scalable and adjustable, however certain programs require different starting points. We love CrossFit, but we also recognize that sometimes people have other goals. Using the depth of classes that we have available allows for a safer and more effective entry point for newer athletes.

What is a typical session like? 

All classes are coached from start to finish by professional coaches. From warm-up to high fives at the end, they’ll guide you through the best hour of your day. We're not DJs and we're not here to yell at you (sorry if that's your style), we're here to be your guide to excellence in movement and building you into a resilient and strong human. Our coaches have over 25 years of strength and conditioning knowledge and you won't find them, or the depth of programming we offer anywhere else. You'll also be working out in our community of amazing and inspiring members.
