Why are you yelling? I understand grunting, I don't think human are capable of lifting heavy ass weights without grunting becoming involuntary, but the fools who actually yell are mostly the gaylords full body half curling 95 pounds in the power rack.
Can you actually Valsalva and yell? I'm not talking about a "GRRG" at the top of a rep, I mean one of those broham "YEEEEARRRG" Goku fucking powering up yells.
