Place one knee on the bench with your shin vertical and your toes pointing up the surface.
Bring your other leg forward into a lunge position with the foot flat on the floor.
Ensure your torso is upright and your hips are facing forward.
Gently tuck your pelvis under (posterior pelvic tilt) to avoid arching your lower back.
Place your hand on the buttock of the kneeling leg and gently guide your hip forward.
Slowly lunge forward until you feel a stretch at the front of the hip and thigh of the kneeling leg.
To vary the stretch, gently rotate the kneeling leg inward (internal rotation) or outward (external rotation) to target different angles of the hip flexors.
Keep your chest tall and avoid leaning excessively forward.
Hold/maintain as prescribed by your physiotherapist.
