The bridge exercise strengthens your abdominal, buttock, and hamstring muscles. This helps keep your back stable and aligned when you walk.
Lie on the floor with your back and palms flat. Bend your knees. Keep your feet flat on the floor.
Contract your abdominal and buttock muscles. Slowly lift your buttocks off the floor until there is a straight line from your knees to your shoulders.
Hold for 5 to 15 seconds. Repeat 5 to10 times.
