This three-minute core series from Barry's Bootcamp trainer Allie Cohen is just what you need to amp up your workout for bikini season. Allie loves tacking this ab-burning circuit to the end of her intense calorie-torching workouts (check out her 25-minute no-equipment workout here) in order to work the core even harder. The result? You'll be ready for any Spring break vacation plans in no time.
Here's a list of the six moves, each performed for 30 seconds with a 30-second rest at the end. Try repeating the entire circuit up to three times, resting for 30 seconds between each circuit, for a 10-minute core workout. Even if you only repeat once, this series works well as an add-on to a total-body workout — or even just a quick way to tone abs while you're watching TV or starting your day.
