The Roman chair is a piece of exercise equipment. The equipment is mainly used for the lower back, but can also target the gluteal muscles, hamstring and the abdominals. The definition of the equipment, and what 'Roman chair exercise' specifically means, is not clear.
Various exercises have been called "Roman chair." The most common or earliest historical meaning for the movement is not clear. Bodyweight can provide significant resistance in all variations, and additional weight can be added to increase difficulty. Mainly two actions are followed while exercising with a "Roman chair"—Inhale and Exhale. Inhale is to bend forward from the hips, lowering the chest towards the floor, while keeping the back straight. Exhale is to straighten the body to return to the start position to complete one rep.
One type of exercise done on a Roman chair is a type of lower-back hyperextension performed to strengthen the lower back, especially the erector spinae. The chair holds a person in place, lying prone, as he or she bends at the waist and then extends the body upward.
