Trainer Harley Pasternak says that he has Lady Gaga do bicycle crunches because the exercise "train(s) her abs from every direction." The real kicker is that Gaga is known to do six sets of 20!
•Lie flat on the floor with your lower back pressed to the ground (pull your abs down to also target your deep abs). Interlace your fingers and put your hands behind your head.
•Bring your knees in toward your chest and lift your shoulder blades 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, 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, which creates the peddling motion. Do this exercise with slow and controlled motion.•Do 10 reps.
