This foodspring video shows you how to do a military plank correctly. This type of plank demands extra balance and strength from your core. Start in a half push-up: your elbows are on the floor under your shoulders, while your shoulders, belly and glutes are tensed. Now raise yourself up higher by putting first one hand, then the other, onto the floor in the place your elbow used to be. You will end up on your hands and toes. Now take it back down one by one until you're back on your elbows and toes. Make sure your hips are always parallel to the floor. Move slowly and make sure your belly and glutes are always tight to keep your stability.
