Sets and reps

Beginner3 sets of as many clean reps as you can, stopping 2 reps short of failure
Muscle growth3–4 sets of 8–15 reps; add a pause or extra load when 15 gets easy
Conditioning2–4 rounds of 30–45 s work, 15–30 s rest

Pick the row that matches your goal. Add weight or reps once every set feels controlled, and log each set so you can see the trend.

Track your progress

Repto shows what you lifted on your last session for every set, suggests your next weight, and starts the rest timer when you tick the set. Your estimated 1-rep max and volume for each exercise are charted over time.
