Bridges: the booty miracle

Lie on your back. Knees bent and feet on floor.

Hold your belly muscles flat. But don't hold your breath.

Squeeze your butt.

Use your butt muscles to lift your hips from the floor 6-8 inches. (make a "bridge", get it?) Slooooowly.

Slooooowly lower your hips back down to the floor.

Repeat 40 times. Take rest breaks often.

When you can do 40 without a rest break, do 2 sets of 40.
