Sweat Is Free®

No shortcuts.

Objective information, individual attention, and consistent work come together in a training environment built around the person.

How we train

Know where you are. Train for what comes next.

Programs are individualized using goals, health and injury history, current abilities, body composition, and relevant medical considerations. Force-output data, respiratory testing, body-composition tracking, and recovery observations can inform training decisions.

Diagnostic sessions take place one-on-one. Group training remains intentionally limited so that coaching and program adjustments stay personal.
