Thing is…you should not listen to anybody but Broz and your own body. Do what Broz says and then go from there.
Work up to the volume, frequency and intensity (weight used).
Read his blog and read what those who work with him say and do.
Be prepared for being tired and not wanting to go to the gym. Go anyway (that is, IF you really want to do what Broz says).
Do not make a hybrid program using bits and pieces from Broz and then something else. it just does not work.
Understand that there are times Broz has to physically pick up his trainees and make them come to the gym to workout.
It is quite the challenge to follow what he says but the rewards are outstanding (and I speak from experience). I brought my squat from 405x3 to 585x6 within 14 months with this type of training BUT it was not easy and it took it’s toll on my social life etc.
Also, plenty of guys do this without steroids. I did. They help of course but are not the end all.
Most importantly is you and your commitment. If you like high frequency training for bodybuilding then perhaps what Broz is doing is not the best for you. remember he has his trainees try for a MAX every day. EVERY DAY!
His focus is strength and speed not size.
If you really feel that this is a good path for you but want size over strength perhaps it is better to look at other coaches who have specialized in high frequency training. Waterbury has some programs where you do a squat movement 4-8 times a week. Coach thib’s programs feature at least 3 squat sessions. And there are plenty of others you can learn from.
Now of course, if you continue this, it is a good idea to load up on fish oil, vit C, b12 and other supplements that help you sleep better and recuperate faster. Going to bed before 11PM will help odd advice but my old coach used to preach this and of course for the longest time we did not BUT when we consistently followed that advice we grew and got stronger faster. So: eat, eat and get quality sleep. If not, you will burn out and lose your gains. Also, remember he said it is better to do something instead of nothing. On the days you feel like total crap, squat the empty bar 30-40 times. But no matter what, try to learn from it as much as you can and use it for the future.
all the best
