my dad gave me this odd exercise device, it looks like a metal bar with handles on each end with a spring in the middle, its meant to be bent in half and that is supposedly good exercise. i figured i could use the exercise soooo yep.

what is this device called? how is it meant to be used EXACTLY? (aside from the obvious)

and my dad claims that its MUCH better and faster than lifting weights (good because i cant stand that anyway) is this true?
XD $andman, i already thought of that one :p
just last night i was wondering how many people have accidentally gotten chest hair, nipples, thier nose (that one's gotta take skill), etc caught in it... but im not the type to go without a shirt anyway, so it works.
