Crossover Kneeling Hip Flexor Stretch

  • Beginner
  • Compound
  • Timed hold
  • Lower legs
  • Waist

This dynamic stretch targets the hip flexors and psoas while incorporating a lateral reach to engage the obliques and core. It is highly effective for improving hip mobility and relieving tension caused by prolonged sitting.

Muscles worked

Primary

  • Glutes
  • Quadriceps

Secondary

  • Hip flexors

Equipment

  • Body weight

Setup

  1. Begin in a half-kneeling position with your right knee on the ground and your left foot planted firmly in front.
  2. Ensure both knees are bent at approximately 90-degree angles with your torso upright.
  3. Engage your core and perform a slight posterior pelvic tilt by tucking your tailbone under.

How to do it

  1. Squeeze your right glute and shift your weight slightly forward until you feel a stretch in the front of your right hip.
  2. Reach your right arm straight up toward the ceiling, then slowly lean your torso toward the left (crossing over the front leg).
  3. Inhale deeply as you reach and lean, then exhale as you hold the peak stretch for 2-3 seconds.
  4. Return to the center position with control and repeat for the desired reps before switching sides.

Form checklist

  • Keep the glute of the kneeling leg squeezed throughout to stabilize the pelvis.
  • Maintain an upright chest and avoid leaning forward at the hips.
  • Ensure the front knee stays aligned over the ankle and does not cave inward.
  • Avoid arching the lower back as you reach overhead.

Pro tips

  • Focus on lengthening the distance between your ribcage and your hip bone to maximize the psoas and oblique stretch.
  • Drive the kneeling knee into the floor to create active tension, which helps the hip flexors relax further into the stretch.

Make it harder

  • Hold the lateral reach for 30 seconds to transition from a dynamic movement to a deep static stretch.
  • Elevate the rear foot on a bench or chair to increase the stretch on the quadriceps.
