We are pumped to share one of our favorite stories from Self here on FitSugar!
Your trainer: Bernie Zurella, a former World Kickboxing Association fighter and Army drill sergeant. He used that butt-kicking background to design these creative exercises for his wait-listed class Butt and Gutt (extra t because it's extra effective) at Gold's Gym in Long Branch, New Jersey. Now you get the exclusive.
You'll need: A stability ball. Size matters‚ see which ball is right for you.
Your plan: Combine these moves with this stability ball ab workout for one awesome workout three times a week. Or pick favorites (two or three, so you're constantly switching it up), and spend 5 minutes daily zeroing in on your trouble zones. Simple.
