In the 90/90 quad stretch, which portion of the quadriceps is targeted?

• A. Distal Quad
• B. Middle Quad
• C. Proximal Quad
• D. Entire Quadriceps

Answer: (C)

The quadriceps are a group that crosses both the hip and knee joints, so changing how the hip and knee bend changes which fibers are lengthened. In the 90/90 quad stretch, the leg being stretched has the hip flexed around 90 degrees and the knee also bent about 90 degrees. This setup places the stretch primarily on the proximal portion of the quadriceps—the fibers near the hip origin (where the rectus femoris and nearby fibers originate). Because the knee is bent, the distal fibers near the knee aren’t under as much stretch, so the emphasis is on the proximal region. That’s why the proximal quad is the best target in this stretch.
