One rep maximum (1RM) in weight training is the max amount of weight one can lift in a single repetition for a given exercise. One repetition maximum can be used for determining an individual's maximum strength and is the method for determining the winner in events such as powerlifting and weightlifting competitions.
One repetition maximum can also be used as an upper limit, in order to determine the desired "load" for an exercise (as a percentage of the 1RM).
With the 1 Rep Max app, you can enter the amount of weight you lifted on a movement and the number of reps to calculate your 1 rep max and various percentages of your one rep max.
For example you lifted 200lbs 3 times. Using this information you can calculate that your max is approximately 212lbs.
This app also can be used to quickly determine a percentage of your one rep max. Many weight programs will tell you to lift 65% of your 1RM for 5 sets of 8 reps. Using the example max from above you can determine that your max is 212 and then click over to 65% and see that you need to lift 138 in this workout.
Use this in conjunction with the Mainsite Track app also available in the app store to create custom workouts.
