What exactly is a spreader-bar?
If you just put a strap round your waist/bum and hooked the front of it onto something, it will pinch in at the sides (try it with your trouser-belt!). The spreader bar has the hook on the middle of it, and has the strap(s) running from one end of it (in front of your left hip) to the other (in front of your right hip). That is, the strap is U-shaped rather than circular. This means there is no pinching inwards.
