How to do it

Lie on your back, hands behind head, knees bent. Alternate bringing opposite elbow to opposite knee, extending the other leg.

  1. 1Feel your obliques and rectus abdominis working as you twist and bring elbow to opposite knee
  2. 2Keep your legs elevated and moving in a pedalling motion to maintain tension
  3. 3Engage your deep core to avoid pulling on your neck

Common mistakes

  • Avoid yanking your head forward; support it lightly with your fingertips
  • Don't let your lower back arch off the mat
  • Avoid moving too fast; control the twist and leg extension
