The butterfly stretch is a simple flexibility exercise that targets the inner thighs, hips, and groin. To perform this stretch, sit on the floor with your back straight and the soles of your feet together. Gently press your knees down towards the ground while keeping your feet close to your body. Hold this position for 15 to 30 seconds to feel a gentle stretch. This stretch can be beneficial for improving flexibility and reducing tension in the lower body. It is often included in warm-up routines for activities like yoga or dance, making it a popular choice for athletes and fitness enthusiasts alike.
