Follow This Belly Fat-Fighting Intervals With a Detox Smoothie

Ready, reset, go! Our Flat-Belly Challenge pairs belly-blasting workouts with fat-burning recipes to help you slim your middle and strengthen your core. Day eight gets your fat melting with a 45-minute interval workout followed by a debloating avocado smoothie.

It's time to step up your fat-blasting running workout with intervals! Get ready to burn some mega calories with this longer 45-minute workout. Set the incline to one percent to prevent shin splints, and as with all our workouts, feel free to increase or decrease speed, depending on your level of fitness. Just note that doing so will alter the amount of calories you burn. Click here for the easily printable PDF of this workout.

Made with fiber-rich avocado to keep things moving along, it's also made with hydrating aloe vera juice and coconut water, as well as toxin-flushing lemon juice to help keep your digestive system feeling happy.
