Today I set a new PR for 3 repetitions of back squat. This also happened to be a PR for 2 reps and even 1 rep. The new benchmarks were set using a low-bar or perhaps hybrid low/high-bar technique. Even so, I think some of that improvement was due to greater strength. Anyway, the new PRs are as follows:
1 rep: 250 lb.
2 reps: 250 lb.
3 reps: 250 lb.
(I'm listing them all individually to make them easier to refer back to.)
