Though 10-11 months of layer sessions, I still see huge differences in performance of clusters from pulls vs. presses.
After a 2RM on SGHP's, I always get 6 cluster reps at 90%, and increase weight 10lbs. 2nd set, same thing: get 6, add 10 lbs. On the other hand, when I press (incline or decline) I start at 86-88% of my 2RM, and almost always have to lower weight on the 2nd or 3rd set (or both!) because I got 3 or fewer cluster reps.
Do you see this difference with your athletes? Is this likely because the pressing muscles are more type IIb fibers? I ask because my RM has increased in my presses, w/ less change in size for triceps and chest. Conversely, my SGHP max has not changed much, but my upper back is starting to get noticed by co-workers. (Thanks for that, by the way!!!)
