Some of the major muscles of the calf include: 1  Gastrocnemius (calf muscle): One of the large muscles of the leg, it connects to the heel. It flexes and extends the foot, ankle, and knee.  Soleus: This muscle extends from the back of the knee to the heel.
Squats are possibly the most fundamental exercise. They are one of the best leg exercises because they work a good percentage of your muscle mass. Proper back squats will help you get stronger, gain muscle, burn fat and tone your entire body more than any other exercise.
