Squat form check (Hyperlordosis)

[Hannibal]

Hey guys,

I've got an exaggerated lumbar curve (hyperlordosis). Whenever I squat heavy weights, my lower back feels like it's been worked. The heavier the weight, the more it feels worked. I got the same problem with deadlifts, but I don't have a video of that right now.

I'm not sure if it's the hyperlordosis that's causing me trouble, or if my squat form is off as well. I do try to flex my abs hard to keep my lower back from overextending.

The stance I use is slightly wider than shoulder width. Looking at the videos it seems I'm bending my hips earlier than my knees, instead of bending both at the same time.

Any feedback would be greatly appreciated.

I see no sign of hyperlordosis in your squat form, although your shirt is baggy.

What I do see, in addition to what you've noted about the hips breaking before the knees, is that you thrust your hips forward at the top of most reps. That could definitely place unnecessary stress on your vertebrae, perhaps of a facet injury nature.

You don't need to almost hump the air at the top. Just stand up.

Also, I actually see a degree of lumbar flexion at the bottom of some of those reps that I think should be controlled more. You're just being too loose with your back in general.

Thanks for the reply, mate.

I've deloaded now to work on my technique, but even now when I concentrating even more on squeezing my abs and pushing my knees out, I still feel like I'm losing my tightness at the bottom of the movement.

The only thing that would come to mind to improve this would be to stretch my hamstrings, but that would be counterproductive to fixing my hyperlordosis.

I'm kind of hesitant to buy a belt at this early lifting stage/weight to see if that helps with flexing my abs.

Any suggestions?
