Every program in the catalogue runs inside Onyx Performance OS, where each set shows a recommended weight calculated from your previous sessions, your morning check-in and the set before it. The app selects a program from your goal, your experience and the days you can train, and explains why. You can switch at any time.
The first seven days are free in the app, then $24.99 a month or $199.99 a year. On the web you pay by card today. Cancel any time and keep access to the end of the period.
