Tells you what to lift next, based on what you actually lifted last.

Most training apps are a logbook. You write down what you did, and deciding what to do next is still your problem. LiftMax does that part for you.

Free to download, with no account and no ads. LiftMax Pro is a one-off unlock.

Next session

Barbell Bench Press

82.5 kg · 4 × 8

From your last 3 sessions and your estimated 1RM trend — rounded to a load you can actually build.

The engine

How it decides

Every set you log updates an estimated one-rep max for that exercise. Prescriptions come off the trend across recent sessions rather than a single good day, so one heavy session doesn't send the next one somewhere you can't follow. The newest session carries four sevenths of the answer, the one before it two, the one before that one — no single rating can ever be more than about half of it.

It also learns how you rate effort. Reps-in-reserve judgement is a skill, and most lifters under-rate what they have left — which quietly drags every prescription too light. LiftMax measures your personal bias and corrects for it.

Come back after time off and it backs the load off

Not by waiting for you to prove the loss with a bad session — by the calendar, before you lift. Under ten days nothing happens, because strength is the slowest thing to decay and a holiday costs almost nothing. Past six weeks it stops scaling, because the loss is no longer predictable from time alone and your next few sessions are better evidence than any curve.

Across the bottom, days since you last trained that exercise; up the side, how much comes off the estimate before the next prescription is priced. The reduction is applied to the estimate, not the finished weight, so the plate rounding and your goal's own percentage band still do their usual jobs against a basis that admits time has passed. There is no counter ramping it back out — the reduced session writes its own estimate, so a lifter who was genuinely detrained climbs back gradually and one who handled it easily rebounds almost at once.

In the app

What it looks like

The Conventional Deadlift screen during a workout. Best set 130 kg for 3, estimated one-rep max 155 kg. The target reads 4 sets of 3 at 135 kg, with two reasons under it: you hit the whole prescription, so standard progression; and you are at 23.5 hard sets for this muscle group this week, past what is usually recoverable, so it trims a set. Below it a suggested warm-up of 55 kg for 5, 80 kg for 3 and 107.5 kg for 2, then the weight and reps for set 1 of 4. — The prescription, and why it is that.

The workout summary for Push Day: 1 hour 4 minutes, 6 lifts, 22 working sets, 95% of the plan completed (22 of 23 planned sets), and new bests on Overhead Press at 52.5 kg for 4 and Barbell Incline Bench Press at 67.5 kg for 6. — What a session ends on.

Front and back body diagrams with the muscles a push session trained shaded by how much work each got: chest 12 sets, shoulders 11.5, triceps 9.5, core 2. — What you actually trained.

The Barbell Bench Press page: estimated one-rep max 97.5 kg, built from 95, 95 and 97.5, a predicted 8-rep max of 77.5 kg, and a strength-level bar from Beginner to Elite placing the lift at Intermediate, 25 kg short of Advanced. — Where each lift stands.

The home screen: this week's sets by day, today's 22 sets across 6 lifts, 3 sessions and 10 new bests this month, a Start Workout button and a button to add a past workout. — Your week, and today's session.

The exercise library: a search box, filter chips for each body part, sort by name, times trained or body part, a button to add a custom exercise, and a list of exercises each showing its muscle group, with a how-to guide and an edit control beside it. — Over 200 exercises, plus your own.

The details

Built for the gym, not the spreadsheet

Weights you can actually load.

The model asks for 83.7 kg. What you get depends on what the weight is made of:

Barbell2.5 kg steps82.5
Dumbbell2 kg steps84
Kettlebell4 kg steps84
Pin stack5 kg steps85

A pound gym gets its own table, not a conversion of this one — 2.5 kg is 5.5 lb, and no barbell anywhere makes that.

Knows when a lift has run out of room.

Mark the top of the rack or the last pin on the stack, and it stops prescribing past what the equipment holds — and says so, rather than letting the weight sit still for weeks looking like a plateau.

“This is the most weight you've said this exercise can be loaded to, so it stays there — add reps or find a heavier setup to keep progressing.”

Warm-up sets calculated before your first working set — a three-rung ramp onto the same plate grid, and nothing at all below a load that doesn't need one.
A rest timer between sets, with an alert when it's up.
Over 200 exercises, with your own additions alongside them, and a how-to guide on every one.
18 routine templates — body parts, splits, or built around the equipment to hand.
Per-exercise overrides when the standard progression doesn't suit a lift.
Personal bests and goals, and where a lift sits against general strength standards.
Log past workouts you did away from the app. Kilograms or pounds.

Privacy

Your data stays yours

No account. No sign-up. No ads.

Everything you enter — your profile, workouts, routines and history — is stored in a database on your own device. There is no server holding your training history, because there is no server.

Back up to your own Google Drive on Android or iCloud on iPhone, so a lost or replaced phone doesn't mean starting over — encrypted if you want, and only if you switch it on. Erase everything from within the app whenever you want.

Pro doesn't change any of that. The purchase is held by Google or Apple against your store account; the app only asks whether that account owns it.

Anonymous crash reports are sent to help fix bugs. They contain technical diagnostics only — never your training data. Details are in the privacy policy.
