How to do a glute bridge
Lie on your back.
Get into the starting position for the glute bridge by lying flat on the floor with your legs extended and your arms by your sides. It's a good idea to use an exercise or yoga mat for cushioning and stability.
Bend your knees so that your feet are flat on the floor, about hip-width apart. Your entire spine should be resting against the floor in a neutral, un-arched position.
