The L-sit is an acrobatic body position in which all body weight rests on the hands, with the torso held in a slightly forward-leaning orientation, with legs held horizontally so that each leg forms a nominal right-angle with the torso. The right-angle causes the body to have a notable "L" shape, hence the name "L-sit". It requires significant abdominal strength. When executing an L-sit, a variety of supports may be used by the performer, including gymnastics apparatus such as the floor, rings, parallel bars or parallettes, or the hands of an adagio partner.
