Watching a bit of this, Israetel wouldn't approve. Without discussing the importance of so-called full range of motion (it can mean different things) you obviously don't
need full range to grow. Jason Huh was another monster who did even shorter range. Ridiculously short on some exercises. I will never have any biceps to speak of, but still try different things. I do lengthened first quarter range reps on preacher machine. I put a folded yoga mat on top of the pad so my arms are completely straight when the weight hits my biceps. The danger zone so I do 15 plus reps and squeeze up the weight. Then on another machine I do top half reps with a 2 count at 90 degrees
