The wall sit strengthens your lower body. Your quadriceps on the fronts of your upper legs remain in a static contraction to support the wall sit. The hamstrings on the backs of your upper legs also remain contracted as you sit. Your glutes contract during the wall sit to keep your body stable and balanced.
The majority of muscles in the leg are considered long muscles, in that they stretch great distances. As these muscles contract and relax, they move skeletal bones to create movement of the body. Smaller muscles help the larger muscles, stabilize joints, help rotate joints, and facilitate other fine-tuned movements.The largest muscle masses in the leg are present in the thigh and the calf.The muscles that make up the quadriceps are the strongest and leanest of all muscles in the body. These four muscles at the front of the thigh are the major extensors (help to extend the leg straight) of the knee.They are: 1  Vastus lateralis: On the outside of the thigh, this is the largest of the quadriceps.ome 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. 2  It flexes and extends the foot, ankle, and knee. 3  Soleus: This muscle extends from the back of the knee to the heel. 4  It is important in walking and standing.
