M son and I I recently started online training with Josh. My son is about to finish week three and I'm done week six.
It's working very well, but it is a tremendous amount of work. My son fir example had a squat max of 255 raw at app 135, 16 years old. He just got done wrestling season and has been eating large and took his weight to app 148.
His last squat workout had him do over 50 reps with 185,maybe 70 % roughly for his max.
I have seen a 25 lb increase in my two board and set rep prs the last two weeks in the deadlift. My best is 585, but I never tried more than one rep at 500 or more before . High top end, but sucking at reps.
It's worth checking it out. No disrespect intended towards 5 3 1, which my son used previously . But he said the difference was night and day in difficulty. I'm making sure his nutrition and rest, stretching etc is on target. Same for myself.
For example my son did an easy 360 fl in his meet last September . He was good for app 380 at the start of this program. He was to do 300,330 x3. Then six sets of four with 300. Rest periods were one minute for the six sets. He missed two reps on one set and had to take 2 and 3 reps on the last two sets. It looked like his brains leaked out of his head. Then he finished the workout.
