RM Calculator uses the seven best formulas for calculating your maxreps (Lombardi, Brzycki, Epley, Mayhew, O'Conner, Wathan, Lander),you can choose one of them, or find an average for the mostaccurate result of possible max reps. Knowing how many repetitionsyou should be doing and could be doing is important to determinehow strong a person is at a certain time and is useful forcompeting in certain sports such as weightlifting or powerlifting,planning routines, both strength and hypertrophy, and more! 1RM(One Repetition Maximum) in weight training, is the maximum amountof force that can be generated in a maximal contraction. Onerepetition maximum can be used to determine the maximum strength ofa person and is the method to determine the winner in sports eventslike powerlifting. 1RM also be used to determine the desired loadfor an exercise (as a percentage of 1RM). The repetition maximum(RM) can be calculated directly by testing highs, or indirectlyusing submaximal estimate. It is preferable to use submaximalestimate because it is safer, faster and less confusing forinexperienced athletes.
