Re: Squat stands w/ spotter arms vs power rack
I realized the utility of a rack when I was learning box squats. Without the pins, there's no way to bail if you need to without destroying the box.
Band work is another issue. They say that you can do band work using heavy dumbbells, but I don't really know. I actually had a bunch of bands come last night, but I haven't had the chance to use them yet. Regardless, the band peg is obviously a lot easier than grabbing a pair of 90 lb. dumbbells every time you want to use accommodating resistance. Chains might be the better solution in this case.
