From the gym
Our 2 week learn to lift program teaches the fundamentals of strength training to help beginners learn to build strength at home or here with the support of a coach and community.
Who this gym is for
People who want a performance-focused space for heavy barbell work, Olympic lifting, powerlifting, or CrossFit-style WODs — athletes and committed lifters who value coaching and a hard-training environment over creature comforts.
What to expect
Expect a gritty, no-frills floor with multiple platforms, racks, bumpers and iron, sleds and functional gear, and few cardio machines or spa-style amenities; the vibe is focused and communal, often loud and coach-led during classes or sessions.
Less ideal for
Not the best fit if you want lots of beginner hand-holding, plush amenities (sauna/pool), or a mainly machine-based, low-impact bodybuilding or steady-state cardio experience.
This location: This location lists personal training and has bodyweight, cardio, free weights and mobility & stretch confirmed on the floor.
