The workout app for friends who lift at different weights

A workout app for friends has to do two jobs: keep each of you on your own program, and make the group visible enough that nobody quietly skips a week. RIRLift does both. Your friends see when you train, every finished workout posts to them, and the weekly board scores sessions against each person's own target, so a friend who benches 95 lb competes on equal terms with one who benches 225.

What friends who train together need from an app

Two friends, one plan, different numbers

Same plan, a long way apart on the bar

Jake and Priya both run the 3-day full-body plan below. Jake has lifted for years; Priya started in the spring. Day B, bench press for 6–10 reps with 2 left.

ExerciseYou loggedNext sessionWhy
Barbell Bench PressJake: 185 lb, 10 / 10 / 10 reps, 2 left190 lb × 6–10Every set reached the top of the range, so the bar goes up one 5 lb step and the rep target resets to 6.
Barbell Bench PressPriya: 95 lb, 9 / 8 / 8 reps, 2 left (target 8)95 lb × 9Her weakest set hit the target, but not the top of the range. Same weight, one more rep.
Leg PressPriya: 180 lb, 15 / 15 / 15 reps, 2 left190 lb × 10–15Top of the 10–15 range on every set: one step up, reps back to 10.

Neither of you looks at the other's weights to decide your own. On the board, both of you got credit for the same session.

Training side by side, egging each other on

Upper day on the 4-day plan, both at the same gym. Target: 8 reps with 2 left on bench, 10 reps with 1 left on the shoulder press.

ExerciseYou loggedNext sessionWhy
Barbell Bench PressSet 1: 185 lb × 8, 4 leftSet 2: 195 lbFour left instead of two: 185 × 41 ÷ 39 ≈ 194.5, rounded to 195 lb.
Barbell Bench PressSet 2: 195 lb × 8, nothing leftSet 3: 195 lbYour friend talked you into a grinder. You still got the reps, so the weight holds. Pushing harder never cuts it.
Dumbbell Shoulder Press50 lb pair × 7, 1 left45 lb pairBelow the 8–12 range: 50 × 37 ÷ 40 ≈ 46, rounded down to the next dumbbell.

Train as hard as the company makes you. The next set adjusts to what you logged, not to what you meant to do.

A friend comes back after a month away

Marcus missed four weeks with work travel. The group's challenge starts Monday and he wants to be on the board from day one.

ExerciseYou loggedNext sessionWhy
Barbell Back SquatLast session: 250 lb × 8, 2 left225 lb × 6–10After three weeks or more away, the app offers Ease back in: one week about 10% lighter, rounded to the plates.
Lat PulldownLast session: 140 lb × 12, 1 left125 lb × 8–12Same easier week across every lift. Pick up where I left off skips it if he kept training on the road.

Marcus counts sessions on the board straight away. The lighter week only changes what's on the bar.

Questions

Do my friends need RIRLift to join?

To see your workouts and be on the board, yes. You can invite friends who don't have it yet, and the invite gets them there.

Is it fair if my friends are much stronger than me?

Yes. The weekly board counts sessions against each person's own weekly target, not pounds lifted. Showing up is what scores.

How long do challenges last?

You choose: 7, 14 or 30 days, head-to-head with one friend or together as a group.

Can we follow the same program?

Yes. Add the same plan and each of you gets your own weights, worked out from your own sets and the reps you had left.

Does it help with accountability if I train alone?

That's what the board is for. Your friends see when you train and when you don't, and it resets every Monday so a bad week doesn't follow you. If two days pass with nothing planned, the Dashboard also offers to pick a time and remind you.
