Amazing news: You don't need hours at the gym and an expensive personal trainer to get abs of steel. Just grab a resistance band and block off ten minutes a day to do a set or two of flutter kicks. Here’s how to feel the burn.
Step 1: Sit on the floor, grab your resistance band and position it around your calves.
Step 2: With your back flat, raise your legs about one foot off the floor. (Be sure to keep them straight.)
Step 3: Move your right leg down and your left leg up as far as they’ll go before returning your feet back to the starting position. Now move your left leg down and your right leg up. This is one rep.
Step 4: Continue the movement for eight to 12 reps and up to three sets, all while remembering to engage your core. (If you’re having trouble, position your hands just under your butt for extra support. You've got this.)
