Custom lifting workouts you build once and run from your Watch

Apple's Custom Workouts are built from a warmup, work and recovery intervals and a cooldown, each set by time, distance or left open. That suits a run or a HIIT block, but a lifting session is exercises, sets, reps and weights. In RIRLift you build that on iPhone, with rep ranges, reps in reserve, rest and supersets, then start it on Apple Watch, log every set there and get the next weight set on your wrist.

What a custom lifting workout needs

Three custom workouts, run from the Watch

A 45-minute push day, built from scratch

You build it on iPhone: bench for 3 × 6–8 at 2 left, incline dumbbells for 3 × 8–12, pressdowns for 3 × 10–15 at 1 left. Then you run it from the Watch.

ExerciseYou loggedNext sessionWhy
Barbell Bench Press175 lb, 8 / 7 / 7 reps, 2 left (target 7)175 lb × 8The weakest set hit today's target. Same weight, one more rep.
Incline Dumbbell Press50 lb, 12 / 12 / 12 reps, 2 left (range 8–12)55 lb × 8Every set at the top of the range: one dumbbell step, reps back to 8.
Cable Triceps Pressdown50 lb, 12 / 12 / 11 reps, 1 left (target 11)50 lb × 12The weakest set made 11. Hold the weight, aim for 12.

You wrote the sets and ranges once. The weights are the app's job from here.

The gym is busy, so you change it on the Watch

Pull day, and the barbells are all in use. You replace the barbell row from the Watch and add face pulls at the end, a lift you've logged before.

ExerciseYou loggedNext sessionWhy
Chest-Supported RowReplaced the barbell row: 100 lb × 12 / 11 / 11, 2 left (target 11, range 8–12)100 lb × 12Its first weight came from your barbell row, adjusted for the machine. The weakest set made its target.
Face PullAdded on the Watch, 2 × 12–15: 40 lb, 15 / 15 reps, 1 left50 lb × 12Both sets at the top of the range you set: one stack step, reps back to 12.

Nothing about the change needed the phone, and both lifts kept their own history.

Two days a week with home dumbbells

A full-body routine for adjustable dumbbells and a bench, run twice a week in the garage with the phone charging inside.

ExerciseYou loggedNext sessionWhy
Goblet Squat40 lb, 12 / 12 / 12 reps, 2 left (range 8–12)45 lb × 8Top of the range on every set at the planned effort: one 5 lb step, reps back to 8.
Flat Dumbbell Press45 lb, 10 / 9 / 9 reps, 2 left (target 9, range 8–12)45 lb × 10The weakest set made today's target. Same dumbbells, one more rep.
Dumbbell Curl25 lb, 12 / 11 / 10 reps, 1 left (target 10, range 8–12)25 lb × 11Same rule on a small lift: the weakest set decides.

A custom routine for two days and one set of dumbbells progresses the same way a gym plan does.

Questions

How do I create a custom workout on Apple Watch?

In Apple's Workout app, turn the Digital Crown to a workout, tap the Goals button, tap Custom, then add a warmup, work and recovery intervals and a cooldown. For a lifting session with sets and weights, build a routine in RIRLift on iPhone and start it from the Watch.

Can I make a custom strength workout with sets and reps?

Yes, in RIRLift. Each exercise in a routine has its sets, rep range, reps in reserve and rest, and the Watch logs weight, reps and reps in reserve for every set.

Can I build the routine on the Watch?

Routines are built on iPhone. During a session on the Watch you can replace, add or remove exercises and set their sets, reps, RIR and rest.

Do I need to enter the weights?

No. A lift you've logged starts from your history; a new one opens at a light estimate and the first set measures you. After that, each set you log sets the next.

Is it free?

Yes. Up to 4 active routines, unlimited workouts and the Apple Watch app are free, with no account. Pro adds unlimited routines and plates per side on the Watch.
