One-RM
One repetition maximum calculator and logger for iOS
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.
