Is that the thing for your forearms? You tie weights to it and then roll them up really slowly and roll them back down slowly.

It's for your abs. Just roll it all over your stomach and after a few weeks you'll have a beach body like Arnie.

From the looks of your hand, OP.
You should really lose alot of weight you fucking fat fuck.
