I've been doing STS for 9 months now. The first time, I did the 3 month rotation and this week I finished a 6 month rotation. I can honestly say that this last one was much harder and much more intense. I lost some body fat. My arms are more toned, and my chest went from a D cup to a B cup, however, my thighs are the same 21" they have always been. On top of doing STS, I run. I am a marathon runner, so I'm definetely getting in the cardio. I also do 2 days of legs per week. One day is the regularly scheduled leg workout and the other is a plyo workout. When will my boobs stop shrinking and my legs start catching up? I don't seem to have fat anywhere else, so I can't figure out what the problem is. My legs just don't have the tone I want.
