Häufig gestellte Fragen

Was is One-Rep-Max (1RM)?

One-Rep-Max is the maximum amount of weight you can lift for a single repetition of a given exercise. It is commonly used to measure strength and program training loads.

Wie accurate are 1RM formulas?

Accuracy varies by individual and rep range. Formulas are most accurate when calculated from 1-5 reps. Higher rep estimates tend to overpredict 1RM. Use multiple formulas and consider the average.

Welche formula should I use?

Epley and Brzycki are the most widely used. Epley tends to be slightly more optimistic at higher reps. Brzycki is conservative. Use the average of multiple formulas for the best estimate.

Wie do I use the plate calculator?

Geben Sie Ihren target weight and bar weight, select which plates your gym has, and the tool will calculate exactly what to load on each side of the barbell.
