One repetition maximum calculator and logger for iOS

license last commit open issues

The 1RM is useful to determine an individual's maximum strength. It's also useful to determine the correct weights (as % of 1RM) when training for a specific goal.

One-RM by default uses the Brzycki formula to calculate the 1RM from a given weight lifted for a certain number of repetitions. You can choose any combination of the formulas of Brzycki, Epley, McGlothin, Mayhew et al., O'Conner et al. and Wathen.

Free
