Muscles worked

Primary

  • Hip flexors

Secondary

  • Abs
  • Obliques

Equipment

  • Foam roller

Setup

  1. Place a foam roller on the floor and lie face down, positioning the roller just below your right hip bone.
  2. Support your upper body on your forearms in a low plank position.
  3. Bend your left leg out to the side at a 90-degree angle (half-frog position) to stabilize your body and control the pressure.

How to do it

  1. Slowly shift your body forward and backward, allowing the roller to move over a small 2-3 inch area just below the hip crease.
  2. Inhale deeply and exhale slowly, consciously relaxing your hip muscles to allow the roller to sink into the deeper tissue.
  3. When you find a particularly tender spot, pause and hold for 20-30 seconds while maintaining steady breathing.
  4. Switch sides and repeat the process for the left iliopsoas.

Form checklist

  • Keep your core lightly engaged to prevent your lower back from sagging or arching excessively.
  • Maintain a neutral neck by looking at the floor directly between your forearms.
  • Move at a very slow pace; rapid rolling triggers a protective contraction rather than a release.
  • Adjust the pressure by shifting more weight onto your forearms and the non-rolling leg.

Pro tips

  • To target the iliacus more effectively, slightly rotate your torso toward the side being rolled to change the angle of pressure.
  • Incorporate 'tack and stretch' by finding a tight spot and slowly bending your knee to a 90-degree angle, then straightening it back out.

Make it harder

  • Use a smaller, firmer tool like a lacrosse ball or a psoas-specific release tool for more localized and deeper pressure.
  • Lift your non-rolling leg off the floor to transfer 100% of your lower body weight onto the roller.
