Thanks for the editing advice ScreenWatcha. I'll keep that in mind for future posts!
SuteBun during the set itself I felt the depth climbing as the reps went on and it's something I plan on hammering hard in the coming weeks, Also, here's a 400x1 single, which is 95% of my goal. Sorry for the bad quality!
cparker, I plan on competing in the USPLA. A friend of mine who's spotted my form before has also commented on my tendency to overarch, although they didn't give me any advice on how to correct it. I'll keep your cues in mind next squat session, thanks!
