How to do it

Lie on your side with your top foot on a bench and bottom leg hanging. Lift your hips to create a straight line, engaging your adductors and core.

  1. 1Engage your inner thigh on the top leg to support your body weight
  2. 2Keep your core braced and hips level throughout the hold
  3. 3You should feel a strong contraction in your adductors and obliques

Common mistakes

  • Don't let your hips sag or rotate forward
  • Avoid holding your breath; maintain steady breathing
  • Don't place the bench too far from your hip, keep it at mid-shin to knee level
