I've done Rippletoe's Starting Strength, Madcow's 5x5, and a few runs of HST. Now I'm looking to change it up. Any recommendations? I've never done a split since my first days at the gym when all I did was endless arm isolation and some chest. Back then I weighed 150 pounds. at 6'2 Since all the programs above I now weigh 200 pounds and have made great gains. I would appreciate any help you guys could give me.
