The hamstring stretch is an exercise designed to improve flexibility in the muscles located at the back of the thigh. To perform this stretch, sit on the floor with one leg extended straight and the other leg bent, bringing the sole of the foot to the inner thigh of the extended leg. Reach forward towards the toes of the extended leg, keeping your back straight, and hold the position for 15-30 seconds. This stretch can help alleviate tightness in the hamstring muscles, which may contribute to discomfort or injury. Regularly incorporating the hamstring stretch into your routine can enhance overall mobility and support better performance in activities like running and cycling.
