Exercise: The Reverse Crunch targets your core, but also uses your legs. Lie on your back on your yoga mat and place your hands along your side, palms down. With your knees slightly bent, lift your legs up and back toward you until you are making an L shape with your body. Press down with your hands and lift your tailbone, no more than about four inches. Pause, then return to your L position and repeat. How to use it: Follow this pattern: Sit to Stand to Overhead Press for 60 seconds, rest for 60 seconds, Reverse Crunch for 60 seconds, rest for 60 seconds. Repeat five times (20 total minutes). Nutrition: Eat high-protein breakfasts. Adding 30 grams of protein within the first 30 minutes of your day has been shown to have many positive effects on your metabolism and increase your body's inclination to burn body fat. Two quick and easy favorites: scrambled eggs with low-fat cheese (feel free to skip the salt in the image), or plain Greek yogurt with chocolate whey protein and berries.
