Since I'm so short of available workout time these days, I'm trying to start a time-crunched splits rotation using just the 30min(ish) weights section from 4 Day Split (which I've just purchased - has yet to arrive) and am thinking about also buying the Gym Style series purely for the shorter premixes to add to my new rotation. Just wondering how different the weight work is between these two series. I'm also not good with push ups (wrist and shoulder issues) and I know Gym Style Chest and Triceps has a ton of those so not sure if I'll be able to sub something else for push ups. How many push ups are in the shorter premix?
