Quad set (static quads)

How to move

Lie on your back with one knee bent and that foot flat, the other leg long on the floor.
Pull the long leg's toes toward you and tighten the front of the thigh, pressing the back of the knee down toward the floor.
Hold for about five seconds, then relax.

Form cues

The kneecap should slide up toward the hip as the thigh tightens.
When it is easy, lift the tightened leg a little: the straight leg raise.

Practice and cautions

No universal dose is assigned. Choose a manageable amount for your current capacity, leave room for controlled repetitions, and allow recovery. A clinician’s individual plan takes priority.

This is movement education, not an assessment or treatment prescription. Stop for sharp or increasing pain, dizziness, numbness or tingling; seek individual guidance for symptoms, injury or restrictions.
