Take a wide of grip as you need to rack the bar. It's usually wider than the deadlift as mine are.
But, God damn. Your thighs must be wrecked. Looks like you're just slamming down 155 straight on your legs. Still land on your legs without bumper plates, but I catch it a little with my arms to and tighten them while descending. And what are you trying to do when you bounce a few times after racking? Just lower your elbows and let the bar travel down. Holding it there forever won't be good for energy.
