Exercise guide

Side Plank Raise

  • Intermediate
  • Compound
  • Timed hold
  • Shoulders
  • Upper legs
  • Waist

The Side Plank Raise is a dynamic core exercise that targets the obliques, glutes, and shoulder stabilizers by moving the hips through a vertical range of motion. It builds lateral stability and functional strength more effectively than a static hold.

  • Abs
  • Deltoids
  • Obliques

Secondary

  • Erector spinae
  • Hip flexors

Equipment

  • Body weight

Setup

  1. Lie on your side with your forearm flat on the floor and your elbow positioned directly under your shoulder.
  2. Stack your feet on top of each other or stagger them (top foot in front) for better balance.
  3. Place your top hand on your hip or reach it toward the ceiling.
  4. Ensure your head, shoulders, hips, and heels are aligned in a straight line.

How to do it

  1. Exhale and drive your bottom hip away from the floor by contracting your obliques and glutes.
  2. Lift until your body forms a straight diagonal line from head to heels, pausing for a second at the top.
  3. Inhale as you slowly lower your hips back down until they lightly graze the floor.
  4. Maintain a controlled tempo, taking roughly two seconds for both the lifting and lowering phases.

Form checklist

  • Keep the elbow directly under the shoulder to avoid unnecessary joint strain.
  • Prevent the hips from rotating forward or backward; keep them stacked vertically.
  • Maintain a neutral neck by looking straight ahead rather than down at your feet.
  • Keep the chest open and avoid slouching the top shoulder forward.

Pro tips

  • Focus on 'pinching' the bottom side of your waist at the top of the movement to maximize oblique recruitment.
  • Press your entire forearm and palm into the floor to better engage the serratus anterior and stabilize the shoulder.

Make it harder

  • Perform the raise with your top leg elevated (star plank raise) to increase glute medius activation.
  • Hold a light dumbbell on your top hip to add external resistance to the lateral chain.
