Squeaky boy has had years to "improve" and he's stuck in the same rut. Sometimes he can struggle to bench 225 for 5 or 6; other times, I've seen him do at least 275 or more for the same number of reps -- and in a more deliberate fashion, at that.
I reckon he takes M1T in a haphazard fashion, and as simple enough to believe that, if he beats his head against a wall long enough, said wall will give way and he'll magically become a better lifter/bodybuilder.
I think the whole thing is sad. This kid with a high alto voice talks all big, but physique-wise, he looks like a fat, skinny jerk-off next to countless thousands of teen bodybuilders. He has people to egg him on to ridiculous monickers like "Sith Lord" and "Terminator," to the point that someone filmed his dumb ass trying to recreate Arnold's intro in the original "Terminator."
I'd advise the kid to find a proper powerlifting mentor and take things from there. He's not remarkably strong for his weight but I reckon he'd be a far better powerlifter than BBer. Depending on what he's taking at the time (and I'm not talking that PJ Braun shit), he's an OK bench presser for how shittily he trains ... maybe Louie Simmons or another PL extraordinaire could actually make something of him.
*laughs*
Of course, that'd mean Jason actually followed some directions to a tee. I'd bet good money he is incapable of that and will forever remain the skinny-fat gym rat who loudly squawks anytime he shits his pants doing a 315 bench. God or powers that be forbid us for thinking how he'll behave in a gym some 15-20 years from now ...
