The stage
Run the workout from your wrist.
The Apple Watch app is where the training actually happens. It holds the prescription, counts the work and the rest, takes every set as you finish it, and stays out of the way in between.
The ring is the timer
Work and rest burn down on a ring of tick cells surrounding seven-segment digits. One revolution is the whole step — so the ring answers “how much is left” before you have read the number.
A rest runs hot as it empties. Work is orange from the start. You can tell which state you are in from across the gym, at a glance, mid-set.
Log the set, rate the effort
Log every set as you finish it: reps, load, and how hard it really was. The RPE strip takes the rating in one tap, because anything longer gets skipped and an unrated set teaches the app nothing.
What you log is what the progression reads later. There is no separate bookkeeping step and nothing to reconcile afterwards.
Cut a rest short, and it remembers
Ready early? End the rest. The app notes it — and if you cut the same rest three workouts running, it offers to shorten the prescription rather than asking you to keep overriding it.
The offer is still an offer. Declining leaves the prescription exactly where you authored it.
Park an exercise when its machine is busy
Somebody is on the rack. Park the exercise and the workout moves on — the exercise stays owed, and the workout comes back to it before it will let itself finish.
That is the difference between parking and abandoning. Parking keeps the debt; abandoning gives it up. The app is explicit about which one you just did.
It does not need your phone
The Watch app runs on its own — no phone required mid-workout, in a gym where yours is in a locker. Your live heart rate and effort are metered through Apple Health while you work.
A workout in progress can hand off between wrist and phone without losing a set, so starting on one and finishing on the other costs nothing.
See it burn down.
Free on the App Store · iPhone, iPad and Apple Watch · Requires iOS 26.1. The Apple Watch app requires watchOS 10 and works independently of the phone.
