A wall sit is an exercise done to strengthen the quadriceps muscles. It is characterized by the two right angles formed by the body, one at the hips and one at the knees.
The person wall sitting places their back against a wall with their feet shoulder width apart and a little ways out from the wall. Then, keeping their back against the wall, they lower their hips until their knees form right angles.
This is a very intense work out for the quadriceps muscles. It can be very painful to hold this position for extended periods of time.
