The progressive overload app that decides on your wrist

A progressive overload app for Apple Watch should change the weight on your wrist: up between sets when you had more left than planned, up next session when every set reached the top of the range, and held when you haven't earned it yet. RIRLift corrects the next set on the Watch itself, and when you finish it sets next session's weights there too, even with the phone at home.

What progressive overload needs from a Watch app

Progressive overload, run from the Watch

Upper day: the first bench set was too easy

A four-day upper/lower plan. Bench is set for 8 reps with 2 left, in a 6–8 range, and you've had 195 on the bar before. The phone is in your bag.

ExerciseYou loggedNext sessionWhy
Barbell Bench PressSet 1: 185 lb × 8, 4 leftSet 2: 195 lb × 812 reps to failure against a target of 10: 185 × 41 ÷ 39 ≈ 194.5, rounded to 195 on the bar.
Barbell Bench PressSet 2: 195 lb × 8, 2 leftSet 3: 195 lb × 8Exactly on plan, so the weight holds.
Incline Dumbbell Press55 lb, 9 / 8 / 8 reps, 2 left (target 8, range 8–12)55 lb × 9The weakest set hit today's target of 8. Same dumbbells, one more rep.

The plan was ten pounds light, and the Watch fixed it before set 2, not after the session.

Upper B: three lifts, three answers

Same plan, two days later. The session finishes on the Watch, which sets the next Upper B before it syncs to the iPhone in your bag.

ExerciseYou loggedNext sessionWhy
Barbell Row155 lb, 10 / 10 / 10 reps, 2 left (range 6–10)160 lb × 6Every set at the top of the range: one 5 lb step, reps back to the bottom.
Lat Pulldown140 lb, 12 / 11 / 10 reps, 1 left (target 11, range 8–12)140 lb × 11The weakest set missed 11, so weight and target both stay.
Dumbbell Lateral Raise20 lb, 20 / 20 / 20 reps, 1 left (range 12–20)25 lb × 12Top of 12–20 on every set: one dumbbell step, reps back to 12.

Overload is a separate decision for every lift, and the weakest set, not the best one, makes it.

A lower day with the phone at home

Monday, Watch only: squats in 5–8 with 2 left, Romanian deadlifts in 8–12. The iPhone stays at home until Wednesday's session is done.

Barbell Back SquatMonday: 225 lb × 8 / 8 / 8, 2 leftWednesday: 230 lb × 5Every set at the top of 5–8: one 5 lb step, reps back to 5. Set on the Watch when Monday's session finished, and on your wrist for Wednesday.
Romanian DeadliftMonday: 185 lb × 10 / 9 / 9, 2 left (target 9)Wednesday: 185 lb × 10The weakest set hit its target: same weight, one more rep.

Questions

Can an Apple Watch track progressive overload?

Not on its own: the Workout app records a lifting session without weights or reps. RIRLift logs weight, reps and reps in reserve per set on the Watch and sets the next weight from them.

How can I track progressive overload?

Log every working set's weight, reps and reps left, and raise the weight only when your weakest set reaches the top of the range. RIRLift makes that check after every session.

Do I need my iPhone with me?

Not during the session. Sessions run and finish on the Watch, with the next set corrected there and next session's weights set there when you finish. They sync to the iPhone later.

Do I need to test my one-rep max?

No. The next weight comes from the set you just did and the set you're aiming for. A new lift starts at a light estimate, and its first set measures you.

Is it free?

Yes. Suggested weights, corrections between sets, progression and the Apple Watch app are free, with no account. Pro adds plates per side on the Watch and Fine-tune for step sizes.
