Lying Prone Quadriceps

An advanced PNF stretching technique for the quadriceps and hip flexors performed with a partner, combining isometric contraction with passive stretching.

Instructions

1. Lay face down on the floor or mat with your partner kneeling beside you.
2. Flex one knee and raise that leg off the ground, attempting to bring your foot as close as possible toward your glutes.
3. Your partner should hold your knee and ankle, stabilizing your leg in this bent position.
4. This is your starting position with the knee flexed and leg bent.
5. Attempt to extend your knee while your partner prevents any actual movement (isometric contraction phase).
6. Push against your partner’s resistance for 10-20 seconds while maintaining steady breathing.
7. After the contraction, completely relax your leg muscles for 2-3 seconds.
8. Your partner then gently pushes your foot further toward your glutes, deepening the quadriceps and hip flexor stretch.
9. Hold this stretched position for 10-20 seconds while maintaining steady breathing.
10. Return to the starting position and repeat on the opposite side.

Tips

• Communicate constantly with your partner about comfort and intensity; stop if you feel sharp pain.
• The isometric contraction phase activates the muscle before stretching, improving flexibility gains through PNF principle.
• Avoid forcing the stretch too deeply; gentle, progressive stretching is safer and more effective than aggressive forcing.
• This advanced technique requires a knowledgeable partner who understands proper PNF stretching protocol.
• Perform this after lower body workouts when muscles are warm and more pliable for optimal results.
• Stop immediately if you feel pain in your lower back or knee; muscle tension in the quad is the goal, not pain.
