10-Minute Super Tabata Ab Workout From Class FitSugar I love the way that Equinox instructor Raneir Pollard teaches his workouts ("with love," as he describes it). This Tabata-inspired ab workout is only 10 minutes but is effective at recruiting the core with a range of holds, planks, and crunch variations. Bonus points if you join him doing jazz hands during six-inch holds! Here are more Tabata workouts you can do right at home — there are plenty.
