The single-leg bridge is another advanced variation of the glute bridge. Only perform this exercise if you've mastered the glute bridge and can maintain proper form throughout the duration of the movement.
Lie on your back, and place your hands on the floor for stability as you bend one leg and lift the other leg off the ground.
Pressing your heel into the floor, lift your pelvis up, keeping your body in a stiff bridge position.
Slowly lower your body to the floor and repeat for 30 seconds on each side.
