Glute Bridge

Lie on you back with your hips and knees flexed, feet on the ground. From this position, raise your butt off of the ground to a height where your body makes a straight line from your knees to your shoulders. To make the exercise more intense, you can add weight by letting a barbell rest on your hips as you complete the motion, or you can put your feet on a slightly higher surface such as a step or a bench.
