I did the GS series twice a week with a rest day inbetween + cardio each day. I did it for 4 week straight, then changed the rotation, and then did S & H for 2 weeks the same way, and now I use all 3, GS, S&H and PS in a rotation, this last rotation is one I really like, but I'm glad I did the GS twice a week and S&H twice a week, it really built up my enduance and strength quickly.
