I'm sure spine curvature is somewhat common even in bodybuilding. I do t see it being a concern competing whatsoever unless someone had an extreme case, in which I doubt they'd be on stage anyways since theur training epuod likely be lacking because of their condition
I'm curious on this too. I have scoliosis also . The curve itself isn't too noticeable but my traps are different sizes and my left shoulder is slightly higher. Also the range of motions are different on each shoulder. I didn't even notice any of this myself until I started weightlifting and watching in the mirror.
I think we are all our worst critics tho!
Do you have any issues with oh squats?
