Squatted 365 off a 10 inch box with no breifs. Never had tried this before, so it was a PR, in the sense that I had never done more than that.
Height of the box makes all the difference in the world, btw. I have done over 600 off a high box (dumbell bench), and recently hit 585 off a 14 inch box, wearing breifs.
But neither of those made me hurt as bad the next day as going raw down to a 10 inch box. Ouch!!! But had to do something, videotaped some free squats and my hips have been locking up an inch or so above parallel, regardless of weight.
I thought I was chickening out a couple Saturdays ago by not going really deep with the 545 or so I was free squatting at Eastside, but then I went RAW a few days after that, and was unable to get 135 any lower than the suited 545 was. Hips just tightened up and locked. I even bounced up and down to try and get lower, but no go.
Hoping that a few months of work on the extremely low box will cure those ills.
