So berechnen Sie One Rep Max Calculator
learn.whatIsHeading
One Rep Max (1RM) is the maximum weight you can lift for one complete repetition of an exercise. It is used to set training loads as percentages of 1RM. Direct 1RM testing is risky for beginners — submaximal prediction formulas estimate it from a set you can perform safely.
Schritt-für-Schritt-Anleitung
- 1Lift a weight for as many reps as possible (ideally 3–10 reps)
- 2Apply prediction formula — Brzycki, Epley, or Lander
- 3Average the results for a more reliable estimate
- 4Set training weights as percentages of estimated 1RM
Gelöste Beispiele
Eingabe
100 kg for 5 reps
Ergebnis
~116 kg 1RM
Brzycki: 100 × 36/(37-5) = 112.5 kg
Eingabe
60 kg for 10 reps
Ergebnis
~80 kg 1RM
Epley: 60 × (1 + 10/30) = 80 kg
