When you head to the gym for a leg workout you may focus on the large muscles of the thighs and hips -- neglecting your lower legs. Taking time to work the calf muscles offers aesthetic and biomechanical benefits. Skipping training for the muscles of the calf can make you prone to injury so make an effort to target them in your next lower body strength-training session. Shapely calves create a desirous aesthetic look. Toned calves compliment a pair of heels!
