Cathe, I can't tell you how much I am enjoying STS. I just started Mesocycle 2, and am wondering if light ab work during the rest periods on the upper body workouts is ok. I'm not talking pikes on the ball or planks or anything that involves upper body, but just 15-20 crunches, side crunches, bike maneuvers... still leaving 20-30 seconds for true rest.
Thank you!
Beth
