I've heard this before, and I am not going to suggest it's without any merit, but I find CGBP extremely hard on the shoulders -- indeed, I find it to work my delts a whole lot. I would advocate for reverse-grip bench presses. (Indeed, I prefer incline presses strongly over flat benching bc of my shoulder issues; flat benching tends to be harder on the A/C joints.) And I would take a break from all overhead work, as well as things that engage the upper traps, and focus on scap retraction and lower and mid trap work, in addition to RC work.
If you check out my log, you will see that I've had a whole bunch of shoulder operations. My bilateral impingement was so intractable that they performed bilateral clavicular distal excision (cut the ends off my collar bone), so I have faux A/C joints.
Where did it all start? Wrestling. Repeated dislocations. And then a short stint of rugby brought even more. Some 23 years later, I learned I am hypermobile and have a connective tissue disorder. No more wrestling or other fun stuff.
Subbed. Good luck with your goals. You're already a strong kid. And big props re the collegiate wrestling!
P.S.
Sean1332 knows a helluva lot more than I will ever know about powerlifting -- and he's also way stronger than I've ever been or will be -- and it's quite possible he has a better understanding than do I re the interplay between power-lifting movements and how they ramify on various injuries. So, to be clear, when he speaks, you ought pay attention.
