Hold. Rest. Repeat… without counting in your head. I built Stretch & Release after I kept losing track of how long I’d held a stretch, or how many reps I still had left. Set your hold time, rest time and reps. Numbers and graphics are easy to read, or close your eyes and use the spoken audio and haptic cues. Use either your iPhone or your Apple Watch — build a set list and it syncs across both devices using iCloud.
