Stripe pays you out — one-time programs or monthly coaching.

Safety

Safeguards for minors 13+.

Our athletes are 13 and older, so the bar is higher. Trainers are verified before they can teach, paid coaching is billed to a parent or guardian, and you only see the progress an athlete has agreed to share — never their weights or age.

Trainer FAQ

Good to know.

Nothing to join or to publish free programs. On paid programs we take a flat 25% — you keep 75%, paid out via Stripe. Free programs cost you nothing.
