Wall BridgeLie on your back with your butt against the wall and arms at your sides. Bend your knees and plant your feet 3 to 4 feet up the wall. Raise your lower and middle back off floor, keeping your shoulder blades on the ground. Hold for a deep inhale, then exhale and slowly return to the starting position.
Cross your right ankle over your left knee so that only your left foot is on wall.
MAKE IT EASIER :
Don't use the wall. Keep your feet flat on floor as you lift into a bridge.
