Enter any 2–3 RM points (1–20 reps). We fit your curve and estimate your full 1–20RM profile.
Use recent sets taken close to failure (0–3 reps in reserve). The more honest the sets, the more accurate your 1–20RM curve.
Each RM point is one heavy set you’ve already done, written as “reps & weight”.
We use these points to fit your load–rep curve and estimate your full 1–20RM profile.
