Side Plank With Rotation

A powerful side plank progression that adds controlled rotation (“thread the needle”) to build anti-rotation strength, thoracic mobility, and shoulder stability in one drill.

Muscles Targeted

Obliques, quadratus lumborum, serratus anterior, scapular stabilizers, glutes.

Key Benefits

  • Builds anti-rotation strength under movement
  • Improves thoracic rotation control
  • Challenges shoulder stability and endurance
  • Great progression from standard side planks
Rotate through the upper back—avoid collapsing at the hips.

Equipment Needed

No equipment required. A mat is optional for comfort.

How to Perform Side Plank With Rotation

  1. Set up in a side plank with elbow under shoulder.
  2. Lift hips so your body forms a straight line.
  3. Reach the top arm up, then rotate and “thread” it under your torso.
  4. Return to the open position with control.
  5. Repeat for reps, then switch sides.

Programming Options

  • 6–12 reps per side
  • 2–4 sets
  • Slow tempo (2 seconds in / 2 seconds out) for more control

When to Use It

Core circuits, warm-ups, thoracic mobility blocks, and later-stage rehab when you want rotation with stability.

Frequently Asked Questions

Should my hips move during the rotation?

Try to keep hips stacked and steady. If you’re rocking a lot, reduce the range or slow down.

Where should I feel this?

Mostly in the side of the trunk and the supporting shoulder. Mild upper-back effort is normal.

How do I make it easier?

Use a modified side plank (bottom knee down) and keep the rotation smaller.
