Copenhagen Adductor Plank

StrengthenAdvanced

Side plank with the upper leg supported on a bench, generating intense eccentric load on the adductors of the upper leg. This is the exercise with the strongest evidence for preventing and treating adductor strain in athletes.

How to perform

  1. Starting position. Lie on your side with the support of a bench, chair, or partner under the upper leg (at knee or shin height).
  2. Step 2. Raise the hips off the floor into side-plank position, supporting on the forearm of the lower side.
  3. Step 3. The upper leg rests on the support; the lower leg hangs in the air.
  4. Step 4. Hold the isometric position for an initial 10 to 30 seconds, progressing to 60 seconds as tolerance allows.
  5. Return. For progression, add movement: actively raise and lower the lower leg (dynamic adduction against gravity) 5 to 10 times during the hold.

When not to perform

  • Adductor strain in acute inflammatory phase
  • Active inguinal hernia
  • Acute pain at the pubic symphysis
  • Recent post-operative hip or inguinal hernia surgery
  • Uncontrolled arterial hypertension
  • Acute low-back pain with radiation
