Your app for time-based training

No sets.
No reps.
Just time.

Clusterproofed replaces rigid sets-times-reps schemes with a fixed time window. Your performance decides how much you get done — not a piece of paper.

Weakness comes on its own.

Clusters
As many clean clusters as possible before time runs out.
The idea

Why a time window instead of a spreadsheet?

Classic training dictates exactly how many reps you have to hit — no matter how you actually feel that day. Clusterproofed flips that around.

Classic

4 sets × 8 reps. Fixed in advance, whether you're strong or wiped out today. The number decides when you're done.

Clusterproofed

15 minutes. As many clusters as possible. The time is fixed — your form on the day decides what you get out of it.

Four modes

One stimulus for every goal

Volume
Density training, moderate weight, lots of clusters.
Build
Muscle growth at moderate weight.
Force
Strength-focused, heavier weight.
Strength
Near-max strength, few heavy clusters.
