<p>I’d like to add what I’ve been doing. My bud and I have been doing full body work-outs 3x a week now. After each one we do pyramids of pull-ups (for example: 1,2,3,4,3,2,1). I started doing pyramids up to 4, and he was doing up to 3. He is now up to 5 (his best PFT max was 7 I think, so this is quite an accomplishment) and I’m up to 7 (which is 49 total in a 5 min period). They have helped our pull-ups remarkably!</p>
