Weight Training Calculator

This calculator estimates how much weight you should use for strength training for different rep range. These should only serve as starting points an act as a guide. There are numerous factors that contribute to your ability to achieve a given load at a particular repetition range.

Those with local muscular endurance may be able to lift heavy loads for high repetitions, while others may find their 15-rep maxes are much lower than the calculator reports due to the fact that their muscles exhaust much earlier.
