A gym in the heart of Jamaica Plain

Mike's Fitness JP has been the neighborhood gym in Jamaica Plain for 20 years, and we're still the biggest independent gym in JP. With more than 15,000 square feet of open space, there's room to move and train without waiting around. You'll find more squat racks than most gyms in the city plus a full range of strength and cardio equipment, so you can follow your own routine at your own pace.

Want more structure? Work one on one with a certified personal trainer, or try our group classes like Spin, Zumba, Pilates Sculpt, Beginners Muay Thai and HIIT Cardio, all easy to book in the app. No contracts, no startup fees and no hidden fees. The price you see is the price you pay.
