Congrats on the PR!!
Listen to PoB, DYS, Ecks on the accessory work relative to yer PR. Me personally, I only test PRs maybe once every quarter.
Nice work, Datsun. Good shit. I can't understand why people roll their eyes to the celing when they squat and deadlift. Haha
It's to keep your spine aligned. I guess it's considered old school, but if you pick a point on the ceiling or area in front of you, you're less apt to turn your head, potentially tweaking your back.
Nice PR OP! I bet you could have hit 535 though, given how you still looked pretty strong after the lift.
If I picked my head up and looked at the ceiling I'd probably pinch a number of nerves. I'm no doc, but that position doesn't look conducive to spinal alignment. Actually looks like it would make it worse. A neutral head position is what would keep the spine "aligned".
