There are a handful of guys built for a pegged shin DL (read: "no quads, lots of hammies") who pull a half ton and then everyone gravitates to that style hoping to pull half a ton.
Most people need to put some knee over the bar, drop the hips a bit and pull from closer to the center of the foot.
From the looks of your second rep on that double, I would offer that you are of the latter class.
The guy who owned the gym I used to lift out of used to throw his other deadlifters at me for coaching. I'd always freeze them after they reset the bar after a heavy(ish) pull, stand up, look at where the bar was over the foot, memorize it. Then we'd do it again, and this time freeze at the bottom, feel the angles, feel the shin position, get all Zen, memorize it all. Then we'd continue to pull from there and fine tune as needed.
Yeah, I went underground.
After my 600 pull last April, I was training for a WNPF national thing. I got sick and was pretty ill for a few months. Old person disease. Lost some weight, got uglier.
My daughter wanted to lift at that contest so I went with her. Still pretty sick. Had just started eating solid food maybe 3 weeks prior. Was going to scratch up until like 10 minutes before my DL flight. But, she really wanted me to lift with her at the meet (my wife was all "are you sure? she's really counting on you pulling.")
Pulled 3 singles in the warm up room in like 5 minutes, went out and went 525, 560 and passed on my third. I was very much done.
Still set a national and state record DL with the 560, raw, 220, 55 - 59 year old. I wanted 600 - 630. Surprised I didn't die on the platform.
My kid set 3 national and 4 state records. She is a natural deadlifter. One of my better genetic pass alongs.
Sorry, this is your thread...........
