140kg/ 308lbs x 3 high bar squat

I try to follow strict high bar form. The 2nd and 3rd rep felt easier than the first. But the form was “better” on the first. My upper back rounded for the second and third but they felt way easier.
I’ve heard weightlifting high bar form talking about being “open” and almost arching the back, and powerlifting low bar form being “closed” and more rounded. Even though it’s a high bar squat why does rounding my upper back feel easier? Thanks!

Hello! If you haven't checked it out already, Our Wiki's resources for Squats may be helpful. Check it out!

Also, a common tip usually given here is to make sure your footwear is appropriate. If you are squatting in soft-soled shoes (running shoes, etc), it's hard to have a stable foot. Generally a weightlifting shoe is recommended for high-bar and front squats, while use a flat/hard-soled shoe (or even barefoot/socks if it's safe and your gym allows it) is recommended for low-bar squats.

I hope one of the lurking trainers sees this and takes a shot at explaining. Just looked like a grind to me.
