Roman chair

Bodyweight can provide significant resistance, while additional weight held by the person exercising increases difficulty.

The body is then lifted to straighten the back again, to return to the start position and complete one repetition (see animation, above).

[2] An exercise more commonly referred to as the wall sit, an isometric movement to build strength in the quadriceps, may also be called the Roman chair.

Rather, the body is held up via a combination of weight bearing on the feet and friction created with the wall by exerting pressure against it.

[citation needed] Another exercise called the "Roman chair squat" requires using the quadriceps dynamically.
