Erica loves incorporating this move into ab day because it's so effective. "[Bicycle crunches are] known time and time again as the best ab move, because it works your obliques to the point of failure in a short amount of time," she said.
- Lie flat on the floor with your lower back pressed to the ground (pull your navel in to also target your deep abs).
- Put your hands behind your head, then bring your knees in toward your chest and lift your shoulder blades off the ground, but be sure not to pull on your neck.
- Straighten your right leg out to about a 45-degree angle to the ground while turning your upper body to the left, bringing your right elbow toward the left knee. Make sure your rib cage is moving and not just your elbows.
- Now switch sides and do the same motion on the other side to complete one rep. Do as many reps as you can in 60 seconds.
