September Challenges! Join me :D

Thanks for this! I couldn't figure out how to do so I typed it all out LOL

wall sit, also known as a Roman Chair, is an exercise done to strengthen the quadriceps muscles.[1] 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. Wall sits are used as a primary strengthening exercise in many sports requiring strong quadriceps like fencing, ice hockey, sailing (mostly small boat racing), skiing and track and field. This exercise is also used as a disciplinary activity in the armed forces. It takes up little space, and can be administered easily in classroom settings to misbehaving soldiers-in-training.

The safety of this exercise is disputed; the knees bear most of the load, especially when held at 90 degrees, so it is a potentially injurious exercise for someone with an existing knee problem
