A bridge exercise is a resistance exercise that focuses on strengthening the abdominal, hip, butt and lower back muscles. The bridge is typically used in yoga and pilates classes, and it is a basic rehabilitation exercise.
A person doing a basic bridge lays on her back with her knees bent and her arms at her sides. She then pushes up with her hips creating a straight line from her knees to her shoulders. The glutes and abs should be squeezed while holding this position for 20 to 30 seconds before laying back on the floor. Alterations to the basic bridge typically have the user raise her arms or legs in the air while doing the basic technique.
