So Im going to switch the focus this week from Yoga to stability ball workouts. Up first is a killer all-in-one ab exercise thats touted as the best single core ab exercise you can do by Baltimore Personal Trainer: Coach Nick Tumminello.

The beginning is a little heavy on the info, but I take his word for it and so do my abs because Ive tried this before and it sucks, in a good way…lol
