I am currently using the Juggernaut 2.0 program which does not really test 1 rep maxes as such. The last set of each session is an AMRAP set for each of the big four exercises. So for example you might have numbers like:-
60KG X 20 Reps.
65KG X 17 Reps.
70KG X 14 Reps.
74KG X 8 Reps.
79KG X 5 Reps.
At the moment I have been plugging these numbers into an estimated 1 rep max formula to have some kind of end figure to measure and analyse strength performance and gain.
I am wondering if this is the most effective metric to use to analyse AMRAP sets given the weight changes from session to session. So, you can’t just measure session1 80KG X 10 reps and session2 80KG X 12 reps and know for sure you are getting stronger.
