I also say go for the Pyramids -- they are a lot less boring than push and pull -- to me, the time just flies with Pyramids.
I did do the push and pull section of Hardcore Muscle video last evening, but I much prefer doing pyramids.
Oddly, the Pyramids were the workout from that series that I dreaded and did last -- but after doing Pyramid workouts, I like them more than any other type of weight training.
But I still see value in Push and Pull and also in Muscle Endurance, Muscle Max (the one from the Hardcore series), MIS, and the other all muscle training videos -- that hit all the muscle groups in one video.
