At this point every lifter knows to squat at least once a week and do heavy compounds. However, one thing that often gets neglected is the calf muscle. The calf muscle is composed of three parts: the lateral gastrocnemius, the medial gastrocnemius, and the soleus. Knowing the anatomy of your calf helps when it comes to training because if you train all three parts frequently, equally, and with multiple sets, your calves will grow. Genetics certainly determines the shape of your calves but ultimately not the size or the strength. So hit those calves and hit them hard!
