Yes, the 'Maximal Strength' would be to increase the 1RM. So your saying that it would make sense to use MxS and the Power-Endurance? Only because MxS means when converted to Power-endurance of any duration, you will be able to complete more reps. So combing MxS at the same time with the Power-Endurance, using the Conjugated Loading Method, one would notice an increase in MxS and in the number of reps performed during the P-E phase. I was using pull-ups as an example, but I will change it to a Clean and Jerk.
My confusion would be if your training 4 days a week on MxS and 2 days a week on some sort of Power-Endurance, would that be way over training of the same movement pattern and the motor units? Thanks for the feedback. This is all hypothetical, but for an understanding for myself.
