Why do you need to calculate your 1RM?

Before beginning any strength-training program, it is advisable that one determines their one-repetition-maximum(1RM) to gauge their current strength level. Resistance training is important for increasing muscular strength and muscle mass, and improving bone density. While demonstrating and teaching good technique is paramount, it also is important that a personal trainer has the ability to properly evaluate how much weight one should be lifting, both to effectively stimulate the muscle and to avoid injury.

The calculator gives you all the relevant loads, which are done simply by multiplying the percentage by your 1RM.
