Has anyone the does high bar squat use a safety squat bar to increase their high bar squat?
Can't say I have... are you a straight Oly lifter? What's your max squat?
Nope. Only o-lifter I know of to have used a safety squat bar was Zach Krych, and that was because he had casts on both wrists at the time.
i haven't but i've been wanting to try it out. i've wanted to stick them into my high volume phase to take some of the stress off the shoulders.
