Seated Knee Extension Stretch (Heel Prop)
Knee · Also called heel prop, seated heel prop, knee extension stretch, TKE stretch
Setup
Begin sitting upright in a firm chair with a second chair facing you. Place your heel on the seat of the second chair so your leg is straight out in front of you, with nothing supporting the back of your knee.
Movement
Relax your leg and let gravity slowly straighten your knee. For a deeper stretch, rest your hands gently on your thigh just above the knee and apply light downward pressure. Hold, then release.
Tip
Keep your back straight and let the stretch come from the weight of your leg — it should feel like a firm stretch, not sharp pain.
