I’m a long-time lurker here with a question concerning how to calculate my 1rm for the 5/3/1 percentages. My problem is that, up until now, I have been doing a straight linear progression program very similar to Starting Strength.
So, my question is, how do I calculate a 1rm off of 3x5 sets? I haven’t performed an actual “max” in I don’t know how long. All help is greatly appreciated.
