1RM & Training Load Calculator
Estimate your one-rep max (1RM) from a lighter set, without testing your maximum, and see the load ranges for each training goal.
Effort baseline
Zones and ideal load
Estimates use Epley, Brzycki, Lander and Lombardi equations. Testing a real 1RM carries injury risk — use proper technique, a spotter or safety pins, and consult a qualified strength coach. Not medical advice.
