Calculate your 1 rep max with this easy to use calculator for weight lifters. Simply enter the weight that you lifted, the number of repetitions you performed, and this app will calculate the maximum weight that you should be able to lift for one repetition without placing your body under the great stress that would normally be needed to perform a maximal one rep.
