1. During a set, tap Record a set (Train: ⋯ on the exercise) or the round Record button above Set done (Focus mode). Allow the camera the first time.
2. Prop your phone up so the whole movement is in view, tap the red button, do the set, tap stop. It stops by itself at one minute. Switch between the front and back camera with the arrows. Want sound (to count reps or tell your coach something)? Tap the mic first; it stays on for next time.
3. Watch it back, then Save video (or Retake).

Two videos per exercise

• Each exercise keeps two: find them under Form videos on its page.
• A new recording replaces the older one, so you always have your latest form to look at.
• Tap ★ Set as benchmark on a video you want to keep as your reference. It's never replaced automatically; new recordings only replace the other one. Set another as the benchmark any time, or delete a video yourself.
