Calves are often overlooked in strength training, but they are essential muscles that control the movement of your ankle joints. Strong calves can prevent ankle issues and help with movements at your foot, such as rising onto your toes, rotating your feet inward and outward, or pulling your toes toward your knees. These movements allow you to jump, run, and walk.
Since the calves are relied upon for the movements you do every day, they are susceptible to strains and injuries. Strong calf muscles can help rehabilitate existing injuries or prevent future damage to the lower leg.
If you have mobility problems, increasing your calf strength can benefit you as they support tendons, such as the Achilles. People with knee pain or plantar fasciitis can improve their symptoms by strengthening their calves. If you have any pains or injuries, check with your doctor before beginning any exercise.

If you are an athlete, strong calves may improve your performance, especially during explosive bursts of power and speed due to the fast-twitch muscle fibers in the calves. If you participate in jumping or fast-moving sports such as basketball, soccer, sprinting, or cycling, it is wise to perform specific calf-strengthening exercises.
Along with other leg muscles, your calf muscles—composed of the gastrocnemius and soleus—provide joint stability at the ankle. The gastrocnemius is the more significant part of the calf muscle that creates its shape. It has two heads that form a diamond shape with a split in the middle you may see if you develop the muscle or are lean. The minor muscle that lies beneath the gastrocnemius is called the soleus.
Many calf exercises strengthen the gastrocnemius and the soleus, while others isolate one or the other. Several weighted and bodyweight exercises will strengthen your calves, but some cardiovascular exercises particularly help them. Don't forget to warm up with mobility work and cool down with stretching after your workout.
