Duro: Gym & Workout Tracker

Track your weekly sets per muscle group against science-based growth zones. See where you're growing, maintaining, or overtraining. Import from Strong or Hevy in one tap.

You want to be bigger. But are you actually doing enough?

Duro shows you exactly where every muscle group stands, every week. Color-coded zones tell you what's growing, what's falling behind, and what needs more work.

That changes how you train. When you can see you're two sets away from the growth zone, you do those two sets. When you see a muscle falling behind, you fix it next session. Week after week, that adds up.

◆ Growth Zones: see which muscles are growing, maintaining, or need more volume ◆ Recovery map: which muscles are ready, which need rest ◆ Strength tracking: E1RM trends, plateau detection, PRs at every rep range ◆ Workout builder: pick a split, get a session matched to your gaps ◆ Import from Strong or Hevy: bring your history, see results from day one

250+ exercises and 20 hand picked programs for every level.

Duro doesn't just track what you did. It tells you if it was enough.
