Capacity

Make the exercise fit

Looking for a stretching app with adjustable difficulty? Capacity lets you change individual movement variations inside a routine.

How the slider works

Choose an easier or harder available version. The session pauses and the movement changes immediately, giving you time to get into position.

Some exercises have options in both directions. Others have fewer alternatives or a single version.

You're in control

  • Difficulty: select supported variations during the routine.
  • Exercise time: adjust durations before starting.
  • Breaks: change break duration during the session.

Capacity doesn't automatically increase difficulty or remember each exercise's setting between sessions. Your default difficulty is the starting point.
