No vid of exactly 275x5, but have one of 265x9 and then 275x3 (where I am pretty sure I had 2 more reps in me if wanted to/had a spotter, but you be the judge):
I took ~10 years off of squatting from 2002-13. I didn't have a squat rack in my home gym during those years and even though I was an above average squatter before that (IMO)--I was just much more...
