How GYMKC sets the weight for this exercise

This exercise starts with your bodyweight. Once you reach 10–20 reps, you add weight in 2.5 kg (5 lb) steps.

GYMKC adds reps before weight. The sets you log also decide when it is time to add weight.

These numbers are an example of how the calculation works. Your actual prescription is recalculated every set from your own records. See how the calculation works
