The Calf Stretch is an exercise designed to improve flexibility in the calf muscles, specifically the gastrocnemius and soleus. It is commonly performed by standing facing a wall, placing one foot behind the other, and leaning forward while keeping the back leg straight. This position helps to elongate the calf muscles, promoting better range of motion. To perform the stretch effectively, hold the position for 15 to 30 seconds and switch legs. It is important to keep the heel of the back foot on the ground to maximize the stretch. Regular practice can help prevent injuries and improve overall lower leg function.
