Definition

The single- or double-leg inverted hurdler's stretch endangers the knee — stretching its medial ligaments, crushing the meniscus, and side-slipping the kneecap.

Detail

The Single- or Double-Leg Inverted Hurdler's Stretch is a seated stretch and one of the contraindicated ("X-Rated") movements, illustrated in the source with a large "X". Its specific risks are:

  • Stretches the medial ligaments of the knee
  • Crushes the meniscus
  • Promotes knee instability
  • Twists and compresses the kneecap, resulting in its side-slipping

Key facts

  • Stretches the medial knee ligaments and crushes the meniscus.
  • Promotes knee instability.
  • Twists/compresses the kneecap, causing it to side-slip.

Knee Joint Range of Motion
The knee is a hinge joint that straightens to about 0° and, in healthy adults, bends to roughly 133–142° depending on age and sex (CDC reference data). The "90°" often quoted is the arc of a seated leg extension, not the knee's full range.
Knee–Toe Relationship Rule
In the squat, manage where the knees travel relative to the toes — keeping the knees from passing the toes versus keeping the spine vertical — and find the "happy medium."
