In 12 weeks, you’ll go from a complete assessment baseline to a trained, coached athlete with real results you can see and feel. This isn’t a generic program. Your workouts are designed around your goals, your body, and your movement quality — reviewed and updated by your assigned coach throughout.
After completing your 12 weeks, your membership transitions to $275/month Individual Design — and you’ll be eligible for our Enhanced Access program, giving you keyless gym entry 7 days a week, 6am–9pm.

You and up to three other like-minded clients train under the close, hands-on supervision of a dedicated coach — but each of you is following your own individualized program. It’s the best of both worlds: the energy of a small community, the precision of personal training.
You’ll also have open access to the gym during regular hours for additional workouts, making this one of the highest-value memberships we offer for adults who want consistent, coached training with real accountability.
