- Lie on a mat with your hands under your buttocks and raise your legs slightly, keeping knees straight and ankles together.
- Keep abs engaged and perform short kicks in an alternating fashion.
- Repeat as needed and then lower legs to the ground.
Do not use your hands to pull your head and neck up during this exercise. Doing so may cause injury. Concentrate on a slow rhythmic cycle from side to side with perfect form for each repetition.
For extra balance training and core strengthening, you can lift one arm or leg.
