Bosu Ball Front Plank

A front plank on a Bosu to add instability and increase deep core and shoulder demands. Great for leveling up plank endurance without crunching.

Muscles Targeted

Deep abs (anti-extension), serratus anterior, shoulders/scapular stabilizers, and glutes.

Key Benefits

  • Increases core demand with instability
  • Improves shoulder stability and control
  • Builds plank endurance without spinal flexion
  • Scales well with shorter holds and better positioning
Think “ribs down, glutes tight.” Instability exposes loss of position fast.

Equipment Needed

Bosu ball and a mat/soft surface.

How to Perform

  1. Place forearms or hands on the Bosu as shown.
  2. Step back into a strong plank position.
  3. Brace your core and keep hips level.
  4. Hold without drifting into a sag or pike.

Programming Options

  • 3–5 holds of 15–40 seconds
  • Rest 45–90 seconds between holds
  • Progress by increasing hold time or adding small rocks

Why This Variation Works

The Bosu forces constant micro-adjustments at the shoulders, which increases the demand on the deep core to stay stacked and neutral.

When to Use It

Core endurance work, shoulder-friendly trunk training, and plank progressions for athletes who need stability under instability.

Frequently Asked Questions

Hands or forearms—what’s better?

Both work. Forearms are often easier on wrists; hands can increase shoulder demand depending on setup.

What if I feel this in my low back?

Shorten the hold, squeeze glutes harder, and slightly tuck pelvis. You can also elevate the Bosu on a stable surface to regress.

How do I make it harder?

Add gentle side-to-side rocks or increase hold time—only if you keep ribs down and hips level.
