Larry Wheels has a fantastic physique, he looks like a built NFL Football player who kept building. the taper, pecs and arms are phenomenal. although I can only imagine him at 350lbs would be dead shortly thereafter.
getting closer, how did it feel to push depth a little? It can take some practice. when I got into olympic lifting my flexibility and ROM developed much better and I finally started hitting good depth, and then eventually A2G, and then I learned the value of a strong lumbar and not allowing it to flex in the hole.

here's a pic I found in my log of my boy burrying a squat last March, he did hit parallel but the screen cap is on the way back up so IMO, he's still above parallel at this point even though the picture perspective isn't the best for catching that aspect of the ROM
But what I like about it, I think this was a 325lb rep for him at the time, is good strong back position, no butt wink, you can't tell here but his heels are firmly planted and his spine is largely in a neutral position even though his chin doesn't look tucked.

just my personal observations and opinions as a guy who's never squatted 405. someone like Hyde who is routinely hitting 500+ would have better feedback. either way, progress is progress and we're proud of you!
