The Bridge Exercise Video

To perform the bridge lie flat on the floor, with your knees bent and your arms by your side.
To begin, lift your bottom up from the floor by pushing through your heels.
Only lift your bottom up as far as feels comfortable, to avoid causing strain on your hips or lower back.

This exercise can be made more difficult by crossing your arms on your chest.

If you bring your feet closer towards your bottom, this will bias your gluteal muscles. Alternatively, if you move your feet away from your bottom, this will target your hamstring muscles.

This exercise may also be performed off a step, or can be made more difficult by performing it on one leg
