Methodology

How My1RM estimates your one-rep max

The formula

Your one-rep max is estimated by averaging three established formulas — Epley, Brzycki, and Lombardi. The estimate is most accurate for sets of 1 to 10 reps; higher-rep sets are shown but are less reliable.

Bodyweight ratios

Each estimated max is divided by your bodyweight to give a strength-to- weight ratio. The SBD total ratio adds squat, bench, and deadlift, then divides by bodyweight.

Percentiles

Percentiles come from a sample table grouped by sex, age, and lift, so treat them as a rough guide rather than an exact rank. They grow more accurate as more real results are added.

Location

A rough city or country label may come from your connection, but it is not precise enough for a true local ranking — so none is shown.
