Technique guide

Set-up

  • Lie on your side next to a bench, with your elbow under your shoulder.
  • Place the inside of your top knee or ankle on the bench, with your bottom leg underneath it.

How to do it

  1. Lift your hips until your body is in a straight line from head to feet.
  2. Hold the position for the prescribed time.
  3. Lower slowly, then repeat on the other side.

Coaching cues

  • Squeeze the top leg down into the bench to lift you.
  • Keep your hips stacked, not rolling forward.

Common mistakes

  • Letting the hips sag towards the floor.
  • Holding your breath.

Safety

  • Start with the knee on the bench rather than the ankle: it is easier on the inner thigh and knee.
