Jee-zus...
475 for 5x5. That is no fucking joke, Will. In fact, that kind of strength is hurtful to my feelings. Very nice job. Ladies and gents, next time you do a 5x5, imagine doing it with 475 fucking pounds.
With that in mind, your knees are punching forward at the bottom on a lot of your reps. I suspect that getting your knees out more will solve this and keep you tighter.
Impressive.
