How to do it

Lie on one side, lift hips off the ground, and hold body straight, supported by one arm and side of the foot.

  1. 1Stack your elbow under your shoulder and lift your hips until your body forms a straight line; you should feel your obliques and glutes working
  2. 2Keep your hips high and your chest open, engaging your core for stability
  3. 3Breathe steadily and hold the position without letting your torso twist

Common mistakes

  • Don't allow your hips to sag or pike up; maintain a straight plank
  • Avoid collapsing into your shoulder, push the floor away to stay lifted
  • Don't hold your breath; breathe evenly throughout the hold

Muscles worked

The side plank mainly works the obliques, with the upper abs, lower abs, and side delts assisting.
