Start Our 21-Day Flat-Belly Challenge Whenever You Want!

Workout: Combine cardio with core work to reap the flat-belly benefits of both types of sweat sessions. This workout alternates between jumping rope and standing ab moves, so you can tone your belly while burning serious calories in just 20 minutes.

Recipe: Think of our Summer quinoa salad as a bulked-up tabbouleh, since detoxifying parsley lays the base of the greens, while a scoop of quinoa and diced avocado provide over 60 percent of your daily recommended fiber — a must-have nutrient if you're looking to support healthy digestion and your flat-belly goals.
