Carmen, I just purchased S&H last week, Have only done 2 of the w/o's so far, they are completely different than GS, I was suprised that I had to go lighter on the wts., at least with upper body, lower I was able to go heavy. My muscles were shaking, I don't think I'll be able to do but a 2 wk rotation with them, I am enjoying it b/c they are so different from her other w/o's., I don't think I am much help!
