How can I effectively perform a towel calf stretch to improve flexibility and reduce tightness in my calf muscles?

To effectively perform a towel calf stretch, sit on the floor with your legs extended in front of you. Place a towel around the ball of your foot and gently pull the towel towards you, keeping your leg straight. Hold the stretch for 15-30 seconds and repeat on the other leg. This stretch can help improve flexibility and reduce tightness in your calf muscles.
