This calculator estimates maximum training weights for the rep range of 1-20. You can use the calculator to estimate your one rep maximum. Or you can use it to
find the right weight for longer sets.
The calculator needs to know how many repetitions you can do (up to 30) at a
weight. You can give information about one or two multi rep records for the exercise.
The results are based on statistical data gleaned from the Internet. There is
specific data for power lifting exercises (squat, bench press and dead lift).
Combined data is used for the other exercises.
