3 months ago I started Cathe's PS Series, loved it, and then moved on to a S&H rotation. I'm just now finishing a Pyramid rotation. It seems that Gym Styles is all I have left if I'm going to stay with a split-routine (due to an injury I'm not doing any cardio right now, so I break up weight training so I can still work out 5 days a week). I see that Gym Styles is very popular around here, but I'm hesitating because I see a lot of positive comments about the weight training in 4DS. How do they compare?
