A workout app with exactly one workout in it.

One program: a four-day split built on heavy compound lifts. Your exercises never change. Your numbers do, and we handle the numbers.

Four days. That's the whole menu.

Other apps sell you a library. All of it is homework. We also train what most programs ignore: neck, tibialis, rotator cuff, grip.

I

Pull

Back, rear delts, traps, biceps, forearms, grip

II

Push

Chest, front & side delts, triceps, serratus

III

Legs

Quads, hamstrings, glutes, adductors, calves, tibialis

IV

Auxiliary

Core, lower back, neck, rotator cuff, carries

We add weight when you've earned it.

Every lift runs on double progression, the method lifters have used for fifty years. We do the bookkeeping.

8 Hit every set

One more rep.

Next session, we ask for one more.

+5 Top out the range

Weight goes up.

We add weight and start your reps over.

6 Miss a set

No penalty.

Log what you got. Your target holds where it is.

Your Session Complete screen. Under Next Session, each lift shows its new target, such as add 5 pounds for 170 by 5.

Warm-up included.
Rest included.
Mobility included.

Cardio, the day's dynamic movements, and ramp-up sets to open. A rest timer that starts itself when you log a set. Ten minutes of mobility to close.

Your exercise screen: Barbell Bench Press with a form figure, four set circles, a rest countdown, and the weight with plus and minus controls.

Your watch mid-exercise: set circles and the weight, with live heart rate in the corner.
Your watch during rest: a countdown at 2:20 and a Skip Rest button.

Everything a session needs.

The exercise screen: form figure, four set circles, the weight.

The right control for every exercise.

Circles for reps. A stopwatch for dead hangs. Countdowns for planks. Distance for carries. We draw the form for every movement.

Your session on the Lock Screen.

Lock your phone and your session stays up: sets, the rest countdown, skip and extend. Timer cues follow your headphones.

The Progress screen: what each main lift has gained since you started.
Rest on the watch, with the next lift named.
A loaded carry on the watch, logged by distance.

Every session logged.

Your progress screen shows what each main lift has gained since you started. Your log holds every set.
