Another thing is his pelvis. I have
a picture here showing some of his back positions during his deadlift setup. I read Lascek's blog that talked a bit about different shapes of pelvises, and I think my friend has a "longer" kind of a pelvis. You can see in the pictures that his lower back is just about always rounded, and when he extends his back, the extension happens more in the thoracic area. His low back looks like a solid lump instead of vertebrae connected to each other, making his lower back look rounded. But I think his back is actually quite good in the middle (tight) picture, if not even overextended in the thoracic area. He loses some of the tightness during the lift, but that's a bit of another issue. I've had him do the "superman" but it didn't really change anything. Am I correct in my analysis?
