The wall sit works the thighs in a static position.
Back against a wall, step your feet forward then lower down until your thighs are parallel to the floor, knees at 90°.
Hold the position, back pressed against the wall, breathing normally.
Your knees stay above your ankles, not in front. Move up a little if the position is too difficult.
