One-Rep Max
Estimate a one-rep max from weight and reps using Epley and Brzycki. A training sketch only — not medical advice.
Frequently asked questions
Is this medical advice?
No. It is a gym estimate. Stop if form breaks and do not use it to diagnose or treat anything.
Which formula should I trust?
Epley and Brzycki diverge as reps climb. Under about 10 reps they usually sit close together.
