To perform the butterfly stretch, follow these steps:
Sit on the floor with your legs extended straight in front of you. Bend your knees and bring the soles of your feet together, allowing your knees to drop to the sides. Hold your feet with your hands and gently pull them towards your groin. Sit up tall, with your spine straight, and lean forward slightly to increase the stretch. Hold the position for 20-30 seconds, breathing deeply, and then release.
