Setup
- Lie face down on the floor, supporting your upper body on your forearms in a modified plank position.
- Place a small-to-medium medicine ball just inside your hip bone (ASIS) on one side of your lower abdomen.
- Extend the opposite leg straight back and bend the knee of the side being worked outward at a 90-degree angle (half-frog position).
How to do it
- Slowly shift your body weight onto the ball, applying firm but tolerable pressure to the iliacus and lower abdominal region.
- Breathe deeply and exhale as you slowly roll your body in small circles or side-to-side over the ball to find trigger points.
- Maintain a slow, controlled tempo, spending 30-60 seconds on one side before switching to the other side.
Form checklist
- Keep your core lightly engaged to prevent your lower back from arching excessively.
- Avoid rolling directly over the hip bone or the floating ribs.
- Maintain deep, diaphragmatic breathing to help the muscles relax into the ball.
- Keep your neck neutral and your shoulders pulled away from your ears.
Pro tips
- For an active release, slowly flex and extend the knee of the leg on the side being rolled to change the tension in the hip flexor.
- Focus on 'melting' into the ball during the exhale rather than tensing up against the pressure.
Make it harder
- Use a smaller, firmer ball (like a lacrosse ball) to increase the localized pressure on the deep tissue.
- Lift the foot of the working leg slightly off the floor to drive more body weight into the medicine ball.
