Sit, feet flat. Place a ball under one foot. Roll from heel to toes, applying gentle pressure. Focus on tight areas. Roll for 1-2 minutes per foot. Repeat on the other foot.
Use a tennis ball for softer pressure, a lacrosse ball for deeper. Maintain a relaxed posture. Perform daily for flexibility. Reduce pressure or consult a professional if you experience sharp pain. Incorporate deep breathing.
