Calves are the lower part of the leg below the knee in human beings. The calves are made up of two muscles, the gastrocnemius, and the soleus.

These muscles work together to plantarflex the foot (pointing the toes down). Both of these muscles are composed of slow-twitch fibers, meaning that they are designed for endurance rather than explosive movement.

The gastrocnemius is the larger of the two muscles and it is located on the outside of the lower leg. This muscle is responsible for most of the power in ankle plantarflexion.

The soleus, on the other hand, is located underneath the gastrocnemius and it works to stabilize the gastrocnemius. It also aids in plantarflexion, but to a lesser extent than the gastrocnemius.

The calves are used in a variety of activities such as walking, running, and jumping. They are also used in sports that require quick movements such as tennis and basketball. Strong calves are important for both everyday activities and athletic performance.

There are a few different ways to train calves. One way is to perform calf raises, which involve standing on your toes and then lowering yourself back down. This exercise can be done with or without weight.

Another way to train the calves is to do sprints or hill repeats. This type of training will help to improve both the strength and endurance of the muscles.

Strong calves will not only improve your performance in various activities, but they can also help to prevent injuries.
