Supine Knee Extension Isometric

SUPINE KNEE EXTENSION ISOMETRIC

The supine knee extension isometric exercise is used to strengthen the knee. Start by lying down on a padded surface placed perpendicular to a wall. Lie down so that your knees are bent in a pain free range with the toes placed against the wall. Begin the exercise by pushing the toes into the wall to isometrically contract the knee extensors. Depending on your goals, hold this contraction for 2 minutes at 20-65% max strength, for 30 seconds at 65-80% max strength, or for 4-8 seconds at max strength.
