Started incorporating low bar squats for volume day (Monday) for 3 reps, 10 sets. I only used 370lbs, but man, it felt tough compared to high bar squat at a higher weight (last week I high bar squatted 410lbs for 10 sets of 3 reps) and my lower back was aching the day after. It's probably going to be a while before I get used to low bar squatting again. I'll be switching back and forth between low and high bar squats every Mondays, Wednesdays and Fridays.
Also, hit a 410lbs paused high bar squats (video) on Wednesday.
Anyways, check these out:
