@jesusrules1978 After doing only S&S for 4 months, coming from a bout of BW training, I had lost no push-up strength/volume when I tested. I did grow my upper chest, which is hit with the TGUs.
If you do the whole thing, including the warm-up, you do hit biceps and quads with the prying goblet squats. I've modified it a bit by doing all the curls on the first squat and increasing from 5 to 10 per set over time. Previously, my max bicep curl 1RM was 17.5kg. Testing this week, I did 2 with a 20kg, so it does work.
I'm also aiming to do the positive part of the squat as explosively as possible. There was no noticeable increase in my squads, but maintaining well.
After 6 months, my forearms, shoulders, and lats have noticeably grown.
I think most of the criticism comes from people who are after a hypertrophy based program, which S&S is not. Some of it also comes from people who don't know/follow the prescribed warm-up either.
