What it is
Stand with your back against a wall, then walk your feet forward and slide down until your thighs are roughly horizontal and your knees are bent to about a right angle. Shins vertical, feet flat, back against the wall. Hold.
Higher than horizontal is easier; lower is harder. That is the dial.
What it demands
Sustained quadriceps contraction with no movement at all — an isometric hold. It is one of the purer examples of a muscle working hard while nothing happens.
Almost no balance, no coordination, and no equipment beyond a wall. It is available to a very wide range of people, which is part of the point.
Nothing much of the hips or the trunk, which is worth saying plainly — this is a narrow exercise, not a leg workout.
What usually goes wrong
Shins angled forward. Feet too close to the wall puts the knees ahead of the ankles and changes the movement. Walking the feet out so the shins are vertical is the standard position.
Sliding up as it gets hard. The thighs drift above horizontal, the effort drops, and the clock keeps running.
Holding the breath. Isometric holds encourage this, and there is no reason to.
Hands on the thighs. Pushing down through the hands takes load off the legs.
Where it sits
A narrow, useful movement: it trains the quadriceps to keep working under sustained load, needs only a wall, and gives an unambiguous signal about how long that lasts.
It is not a substitute for the bodyweight squat, because it involves no movement and no hip work. It is a good companion to one, and a reasonable option when space is very limited or when a movement through range is not available.
