Crisscross – The second most popular Pilates abdominal exercise, you can do the crisscross by first slightly raising your head. While doing the movements, bring your knees toward your chest. Position your hands gently just at the back of your head, but make sure not to interlace your fingers. From here, inhale slowly and twist your position to the right. Bring the left of your elbow toward your right knee, but make sure you extended your right leg. Now, start to inhale and go back to the initial position. Make sure to repeat the step in five sets.
