Hi Chris, I want to try your undulating STS rotation, but wanted to know if you take a rest week at all or do you go straight through all 12 weeks? I am currently in my 3rd round of STS. I am not getting as good results as I did the first time around (I did 3 1/2 mo, then I did 5 1/2 mo now I'm doing 3 1/2 mo again). I think your rotation is just what I need. Thank you!
