What is Quadruped Leg Extension?

Quadruped Leg Extension is an easy, low-impact bodyweight exercise performed on hands and knees that extends one leg back to target the glutes, hamstrings, core, and lower back. It develops hip extension and spinal stability, making it ideal for warm-ups and beginners building posterior chain control.

How to Do Quadruped Leg Extension

  1. Setup position: Start on hands and knees with wrists under shoulders, knees under hips, and a neutral spine. Spread fingers and grip the floor for stability.
  2. Engage core: Brace your core and draw the ribcage down to maintain spinal neutrality. Keep hips level and avoid arching or rotating before moving the leg.
  3. Extend leg back: Slowly raise one leg straight back, pointing the toes and squeezing the glute. Reach the foot back rather than up to emphasize hip extension.
  4. Pause and squeeze: Hold at full extension for one to two seconds, keeping the pelvis stable and breathing steadily. Avoid lifting the opposite hip or rotating the torso.
  5. Return and repeat: Lower the leg with control back to the start, then switch sides. Perform controlled repetitions to build strength and stop if you feel pain.

Frequently Asked Questions

What are the benefits of Quadruped Leg Extension?

This exercise strengthens the glutes, hamstrings, and lower back while improving hip stability and core control. It’s low-impact, useful as a warm-up or rehab tool, and helps build coordination and posterior chain endurance for safer movement patterns.

What common mistakes should I avoid?

Avoid overarching the lower back, rotating or hiking the hips, and using momentum. Keep wrists and knees aligned, engage the core, and move slowly. Lifting the leg too high reduces effectiveness and can stress the lumbar spine.

How can I progress or modify this exercise?

Modify by limiting range of motion or holding the foot closer to the floor. Progress by increasing hold time, adding ankle weights, performing full bird-dog variations, or moving to single-leg glute bridges for greater load and challenge.
