Check Points:

  • Tighten the abdominal muscles in the starting position and maintain this contraction throughout the exercise.
  • The head should be off the ground with the chin slightly tucked.
  • Ensure that the hips and knees maintain 90-degree angles.
  • Keep the feet and knees together throughout the exercise.
  • Attempt to rotate the legs to about 8 to 10 inches off the ground. The opposite shoulder must remain in contact with the ground.

Precautions: This exercise is always performed at a slow cadence. Do not rotate the legs to a point beyond which the opposite arm and shoulder can no longer maintain contact with the ground.
