Keep the workout experience
A 500+ movement library, reusable templates, and an AI builder that drafts periodized programs in seconds — then you fine-tune every set.
More than a workout tracker
Flex vs. standalone fitness tracking software
A standalone fitness tracking app is great at one thing: logging workouts and showing progress. But your business is more than workouts. You still need a way to fill classes, take payments, manage clients, and look professional online.
Flex includes a full workout builder and progress tracking — the part a fitness app does — and then adds the scheduling, payments, and website that actually run the business around it.

Charts clients actually open
Progress tracking lives in the member portal next to their bookings and payments, so clients stay engaged and renew.
