today i did some DE squats and video taped it. after i was all set i took a look and noticed that i was rounding my upper back at the bottom of the lift.

my head is back, by eyes are straight up, my chest is up until i get right towards the bottom and i do a little dip thing with my upper back and then as soon as i start coming back up its not rounded anymore.

is this a flexibility issue or a strength issue? i was only using about 40% of 1RM but it was still very clear that my upper back is rounding.

if i get around to it tomorrow i will set up a youtube account and load up the video so i can show you exactly what i mean.
