Question: are bench and squat bars the same?
Answer: Power bars, used for squat, bench, deadlift, and the like, are the same size and shape as men's Olympic bars. They tend to be stiffer (less whippy) and the collars will probably not spin as easily. If they're not 44 pounds, they'll be 45. ... Normally, the bar in a squat rack will be a regular power bar.
