Setup
- Sit on the floor with your knees bent and feet flat, placing a medicine ball directly under your right glute.
- Cross your right ankle over your left knee in a 'figure-four' position to stretch and expose the piriformis.
- Place your hands on the floor behind you for support and balance.
How to do it
- Shift your weight slightly toward the right hip, applying direct pressure into the medicine ball.
- Slowly roll in small circles or back-and-forth motions to identify areas of tension or 'trigger points'.
- Inhale deeply and, as you exhale, hold your position on any sensitive spots for 20-30 seconds to allow the muscle to release.
- Maintain a slow, controlled tempo, using your hands and left foot to regulate the amount of pressure applied.
Form checklist
- Keep your chest lifted and avoid shrugging your shoulders toward your ears.
- Ensure the ball stays on the fleshy part of the glute and avoid rolling directly onto the hip bone or tailbone.
- Maintain the figure-four leg lock to keep the target muscle under a slight stretch.
- Keep your breathing steady and deep; do not hold your breath when you feel discomfort.
Pro tips
- Focus on 'melting' into the ball rather than tensing up; the more relaxed the muscle is, the deeper the release will be.
- If you find a particularly tight spot, try small internal and external rotations of the hip to work the tissue from different angles.
Make it harder
- Lean further into the side being rolled to increase the percentage of body weight applied to the ball.
- Switch to a smaller, firmer ball (like a lacrosse ball) for more concentrated, deep-tissue pressure.
