Most programs call for a certain number of reps at a percentage of 1 RM, for example, 75%x5. I have been looking at a few programs including 5/3/1 and when I calculate the weight based on my 1 RM I come up with a ridiculously light weight for the number of reps. I wonder if it is that I have a weak 1 RM relative to my higher rep strength which is throwing off the program percentages.
It seems I have two options; I could use a weight that I can lift for 5 times if the program calls for 75%x5, or I could do exactly what the program recommends even though I would not be even approaching failure for that set.
I would appreciate any thoughts or advice you might have.
