There's conventional, snatch grip, and zercher deadlift in the video above. In conventional, I think the weight is not on my heels enough. Snatch grip and zercher, I really have no idea how those should be done properly, so I won't write anything. Also, I'm lowering the weight down extra slowly and using straps, because I have people living under me, we don't get on very well, and the floor isn't very strong... so even the smallest bump with the weights against the floor might cause me problems - and I really don't want to risk the bar falling out of my hands. I do additional grip training, so grip strength should be fine.
