Place the stability ball on the ground and kneel in front of it. Place your right foot on top of the stability ball, with your knee bent at a 90-degree angle. Extend your left leg behind you, keeping it straight. Lean forward, pushing your hips towards the stability ball, until you feel a stretch in your right hip flexor. Hold the stretch for 20-30 seconds, then switch sides and repeat.
