Does anybody else think JW’s formula for calculating 1RM from a rep set gives too high a figure? Or maybe it’s to allow for the 1 or 2 reps ‘left in the tank’ as Jim doesn’r reccomend going to failure.
Use the formula on a 1RM and you get a figure of 3.33% more.
Maybe (Weight x (reps-1) x 0.333) +Weight would give a better answer?
(Yes I KNOW I’m over thinking it, I’ made that way! And I KNOW it doesn’t really matter which formula you use, its all about progressing.)
