Calves are a muscle group that is typically neglected when it comes to weight training and fitness in general. Many people avoid focusing on the calf muscles because they think that they get enough work through other exercises and daily use. Not only is this not the case, but it can cause you problems down the line as well. An imbalance in the development of these different muscle groups are huge contributors to posture and biomechanical issues which can not only decrease athletic performance but can become a quality of life issue as well. No one want to walk around with joint pain and discomfort because of poor posture, especially when it is avoidable as in the case of neglecting to train your calves. Do yourself a favor and take a day every week or so to give your calves the attention that they need.
