Why do fatty boombatties love the ab machine? The other day I was at the gym ripping up the cables like I'm Jesus on the cross. Right across from me is the ab machine. The kind where you hold the bars that sit above your head and you do a crunch motion. This slovenly, greaseball behemoth saunters over to the machine and starts doing crunches. This woman had to be upwards of 250 lbs. Do they think this is doing their belly fat any favor?
