Gym, Martial Arts, and Yoga in Milton, MA

Muscle & Flow was built to challenge the typical gym experience; no gimmicks, no fluff, just real work. What started as a small, à la carte fitness concept has grown into a full-service training facility with over 900 members, a team of 20+ fitness professionals, and a community that pushes to get better every day.

‍

We’re located in the heart of Milton and designed for people who take their fitness - and themselves - seriously. Our space offers three full floors of fitness experiences - The Fight Club, The Gym, and The Studio - where we combine top-tier personal training, a full class schedule, and open gym access all under one roof. Whether you're here to lift, box, flow, or recover, we offer flexibility without compromise. You won’t find cookie-cutter memberships here - only options that fit how you actually train. Our à la carte  model allows you to craft a membership that  includes only the services you're using. 

Our team is made up of dedicated professionals who continually invest in their craft, mentally and physically, to give you the best possible experience. We believe in showing up, putting in the work, and leaving just a little better than you came in. That means training hard, recovering smart, and staying connected to why you started.

If you're looking for an environment that values effort, growth, and grit — welcome to Muscle & Flow.
