Bridge core exercise
The Bridge core exercise is one of my top favorite exercises. In this exercise, start out on the back with elbows by the side. Feet are pointed forward, about a shoulder width apart. Using arms, shoulders and feet, push ribs and directly up from the floor and hold for at least ten seconds. Elbows can be used to stabilize the body during this exercise.
