Copenhagen Adduction Exercise (CAE) Med Ball Isometric Variation

An isometric Copenhagen adduction variation using a medicine ball to challenge groin strength, pelvic control, and lateral trunk stability.

Muscles Targeted

Hip adductors including adductor longus, adductor brevis, adductor magnus, gracilis, and pectineus, with additional demand on the obliques, quadratus lumborum, gluteal stabilizers, and trunk muscles that help maintain a controlled side-plank position.

Key Benefits

  • Builds isometric adductor and groin strength
  • Challenges pelvic and trunk control in a Copenhagen position
  • Uses the medicine ball to create a different support and stability demand
  • Provides a progression or variation from traditional Copenhagen holds
  • Can be useful for athletes who need stronger adductors for running, cutting, and change of direction
Keep the hips lifted and the trunk long rather than allowing the pelvis to sag or rotate. Use a stable medicine ball setup and a position you can control throughout the entire hold.

Equipment Needed

A medicine ball and a comfortable floor surface or mat.

How to Perform the Copenhagen Adduction Exercise Med Ball Isometric Variation

  1. Set up on your side with the working top leg supported on the medicine ball.
  2. Place the forearm under the shoulder and organize the trunk in a strong side-plank position.
  3. Press the supported leg into the medicine ball and lift the hips away from the floor.
  4. Maintain a straight, controlled line through the trunk and pelvis.
  5. Hold the position without allowing the hips to drop or rotate.
  6. Breathe normally while maintaining steady adductor tension.
  7. Lower under control, reset, and repeat on the opposite side.

Programming Options

  • Begin with shorter isometric holds and increase duration as control improves
  • Use a stable ball position before increasing the challenge
  • Keep the emphasis on strong adductor tension rather than maximizing hold time with poor position
  • Use after easier adductor squeezes and supported Copenhagen variations are well tolerated
  • Progress toward more dynamic Copenhagen variations when appropriate

Why This Variation Works

The Copenhagen adduction exercise creates a high demand on the adductors while also requiring the trunk and pelvis to resist unwanted motion. Using a medicine ball changes the support surface and adds a stability challenge while the isometric hold allows sustained groin loading without repeated movement.

When to Use It

Use this variation when progressing beyond basic adductor isometrics and traditional Copenhagen holds, especially for athletes building groin strength and pelvic control for running, sprinting, cutting, field sports, and return-to-sport training.

Frequently Asked Questions

Where should I feel this exercise?

You should primarily feel the inner thigh and groin of the supported top leg, with the side of the trunk also working to maintain the plank position.

Why use a medicine ball?

The medicine ball changes the support surface and can add a stability challenge while you maintain the isometric Copenhagen position.

What if I cannot keep my hips up?

Shorten the hold or regress to an easier Copenhagen variation with a more stable support surface until you can maintain a level pelvis.

Should this be painful in the groin?

The adductors should work hard, but the exercise should not create sharp or worsening pain. Reduce the difficulty if the position is not well tolerated.

Is this a beginner Copenhagen variation?

Usually no. It is better used after basic adductor isometrics and more stable Copenhagen variations can be performed with good control.
