The wall sit requires you to hold yourself in a seated position, (hence the name) for a certain amount of time, normally between 30 to 60 seconds. It predominantly works your glutes, quads, hamstrings …and your pain threshold. A handy feature of the wall sit is that you require no exercise to perform it – perfect for doing at home! All you need is a wall or any other vertical surface to lean against and you’re good to go!
