When traditional crunches just don’t cut it, it’s time to bring in the big guns. It’s bicycle crunch time, friends! It’s easy to perform, too. Lie flat on the floor with your lower back on the ground. Place your hands behind your head, and bring your knees in towards your chest and lift your shoulder blade off the ground. Straighten your right leg out to about a 45-degree angle to the ground while turning your upper body to the left, and bringing your right elbow toward your left knee. Make sure your rib cage is moving and not just your elbows. Now switch sides and do the same motion. Shoot for 2-3 sets of 20.
