A 5x5 app that adds the weight when you earn it

A 5x5 app has one job: tell you what to put on the bar today, and add weight only when all five sets of five went up. RIRLift does that for free on iPhone and Apple Watch. You log reps and how many you had left, it adds one plate step when every set lands, holds when one falls short, and offers a lighter week when a lift stops moving.

What a 5x5 lifter needs from an app

A 5x5 block, session by session

Week 2, Workout A: squat, bench, row

Five sets of exactly 5 on each lift, aiming to finish each set with 2 reps left. Plates go down to 2.5 lb, so the smallest jump is 5 lb.

ExerciseYou loggedNext sessionWhy
Barbell Back Squat185 lb, 5 / 5 / 5 / 5 / 5, 2 left190 lb × 5Every set hit 5 at the planned effort. One step up.
Barbell Bench Press135 lb, 5 / 5 / 5 / 4 / 4, 1 left135 lb × 5The weakest set stopped at 4, so the weight holds. Five sets of five at 135 is still the target.
Barbell RowSet 1: 115 lb × 5, 4 left · sets 2–5: 120 lb × 5, 2 left125 lb × 5Set 1 had two more reps left than planned, so set 2 went up: 115 × 38 ÷ 36 ≈ 121, loaded as 120. Every set at 120 hit 5 on plan: one step up.

Three lifts, three different answers, all from the same five-sets-of-five rule. You never decide on the gym floor.

Workout B: adjusting between sets

Same block, Workout B. The first set of each lift tells the app whether today's weight was right.

ExerciseYou loggedNext sessionWhy
Barbell Overhead Press85 lb, 5 reps, 4 left (planned 2)90 lb for set 2You had two more reps than planned. 85 × 38 ÷ 36 ≈ 90 lb, a weight you can load.
Barbell Deadlift225 lb, 4 reps, nothing left205 lb for the next setBelow the 5 you were asked for. 225 × 33 ÷ 36 ≈ 206, rounded to 205 lb.
Barbell Back Squat205 lb, 5 reps, 1 left (planned 2)205 lbYou got all 5 reps, just closer to failure than planned. The weight holds; you aren't cut for pushing.

A bad first set doesn't cost you the session. The next set is corrected, and the change is marked as a correction.

Week 7: the bench press stops moving

Linear progress always runs out, upper-body lifts first. Here bench and overhead press have stopped adding reps for three sessions.

ExerciseYou loggedNext sessionWhy
Barbell Bench Press155 lb, 5 / 5 / 4 / 4 / 3, third session in a row140 lb × 5 if you tap DeloadNo new rep in three sessions. The recap offers about 10% lighter: 155 × 0.9 ≈ 140 lb.
Barbell Overhead Press95 lb, 5 / 4 / 4 / 4 / 3, third session in a row85 lb × 5 if you tap DeloadSame stall, same offer: 95 × 0.9 ≈ 85 lb. Tap Not yet to keep trying at 95.
Barbell Back Squat245 lb, 5 / 5 / 5 / 5 / 5, 2 left250 lb × 5The squat is still moving, so it keeps climbing. Deloads are per lift.

The lift that stalled backs off; the ones still moving keep going. You decide, the app does the arithmetic.

Questions

Is there a free 5x5 app?

Yes. RIRLift's free tier includes unlimited workouts, the weight suggestions, progression, deload offers and up to 4 active routines. A 5x5 uses two. No account and no ads.

Can I run a StrongLifts-style 5x5 in RIRLift?

Yes. Two alternating workouts, five sets of five, three days a week, weight added when every set lands and a lighter week offered after repeated misses. You build the two routines once; the app runs them.

How much weight should I add each workout?

One step on your equipment when every set hits 5: usually 5 lb on the bar. If every set was clearly easier than planned, the jump can be two steps. It never jumps more than that.

What happens when I fail a weight?

Miss a rep and the weight holds next session. After three sessions with no new rep, the recap suggests about 10% lighter and you choose. A single missed workout changes nothing.

What should I run after 5x5?

When fives stop moving, most lifters switch to fewer heavy sets plus lighter volume. See GZCLP, the Texas Method, or the heavy/moderate/light plan above.
