Oh really? Then surely you must recommend that he only use a Buffalo Bar or Cambered Bar, right? Why wouldn't he, if he needs to get to the most stretched under load? Why do people do a bench press with a standard olympic bar at all anymore, then?<Lmaoo>
Additionally, not everyone lifts with the goal of sarcoplasmic hypertrophy. As a matter of fact, most combat athletes do not train for that purpose. Being near the weight limit of HW, there isn't really any advantage of him gaining size.
For context: with long arms, you can be at full stretch (or close enough to it to reap the benefits of maximal stretch) before touching the chest. Pectoral stretch is not maximal at chest touching, it's maximal where it's maximal for each person's anatomical features including injuries and flexibility. Most people with average length arms without injury would have that be below parallel, which is where things like Buffalo bars, cambered bars and dumbbells are available to take advantage of the stretch. SP has a 84" reach, he's a prime candidate to not need to touch the chest for optimal benefit from BBBP, if that is his aim. Given we don't know his program in context to frequency, intensity, volume, whether this is a main lift or an accessory, or on a circuit, blah blah blah... asserting he needs to touch his chest is silly. It's also completely in the absence of known injuries or ROM limiters that he may have. Even as simple as catching one of my patented teeps to the sternum will prevent you from touching the bar to your chest for a week or two.
You just don't have any idea as to what you're talking about other than regurgitating what you heard some gym bro tell you. Try not to comment on things you only have a cursory understanding of, especially in context to how someone should be performing an exercise without any basis to assert it other than your beginner level knowledge. Cheers.
