Side Bridge - Side Plank

The side plank is one of the best exercises for the obliques and deep core stabilizers, building strength that a straight-ahead crunch can't reach.

Muscles worked

Obliques, Core stabilizers, Shoulders

A static hold performed on one side of the body, building strength and stability in the obliques and deep core muscles.

How to do it

  1. Lie on your side, propped up on one forearm, elbow directly under your shoulder.
  2. Stack your feet on top of each other and lift your hips off the floor.
  3. Form a straight line from your head to your feet.
  4. Hold the position, keeping your core tight and hips lifted.
  5. Lower down under control, then repeat on the other side.

Coaching tips

  • Keep your hips lifted throughout — sagging reduces the effectiveness of the hold.
  • Start with shorter holds and build up duration as your core strength improves.
  • Stack your top foot on your bottom foot, or stagger them slightly, for better balance.

Common mistakes

  • Letting the hips sag toward the floor during the hold.
  • Rotating the torso forward or backward instead of staying stacked.

Frequently asked questions
