One-Rep Max Calculator
Estimate your one-rep max (1RM) from a weight-and-reps set, then use the training percentages to plan working weights. Great for beginners and advanced lifters when you don’t want to test a true max.
How This 1RM Estimate Works
A 1RM estimate uses a common strength formula to approximate your max based on submaximal reps. The training percentages help you pick weights for strength work, technique practice, or hypertrophy blocks.
Use “Load Plates” to see the exact plates for each percentage, or “Warm-Ups” to ramp into that weight.
