Box squats are all my pro strongman training buddy does, and I'm on his program so it's the only kind of squat I currently do as well. However, the topic says "raw lifter" so I assume that means for a raw powerlifter, I'm not a powerlifter and since the (barbell) squat isn't typically a strongman event, I'm not training to improve my back squat like a powerlifter would, I squat as an accessory for strongman events, so the focus is quite a bit different than a powerlifter.
