New to this site, but I have been lifting for a little while. I would like some constructive critisism on my deadlifts and squats. I took a couple videos of single reps in the gym the other day. They arn't the heaviest I've lifted but what I'm working with now. The weights arn't big but I want them to get bigger. Looking at the videos now I can myself see some problems (especially with the deadlift). If you see something please tell me what it is, how to prevent it, and perhaps an assistant exercise to help the problem. I wear a belt and wrist straps when I get over 275lbs. I also wear knee sleeves because I have had a couple knee problems in the past, one related to bad squat form, other one not. I am currently doing a wave loading type routine. Example, Deadlift 290lbs-set of 5 and a set of 3, 310lbs-set of 1, 300lbs-set of 5 and a set of 3, 320-set of 1, 290-dropset. Doing a similar thing for squats but with different weights. Heres my stats and videos. Thank you for the help.
Squat looks fine IMO, not picture perfect because of the weight you are using, but if you were doing a lighter weight, I don't think there would be much to criticize.
Deadlift is decent too, but it seems like you are using your spinal erectors too much instead of your glutes. Hard to tell for sure because it is hidden behind the plates, but it seems like you try to finish by extending your back rather than extending your hips. Try to set your back hard in the beginning and don't let it flatten or round (easier to say than do).
The starting position of the bar also seems a little too far from your shins. When you come up, the bar is still pretty far out in front of you, it isn't dragging up your thighs.
