Four easy exercises to get you into your little party dress

Lie on back with knees bent, palms down, feet hip-width apart. Press into heels and lift hips up. Keeping hips square, raise one leg to a 45-degree angle. Squeeze glutes and hold for three counts. Do 10 reps. Switch sides.

Perfect your form: Engage core to keep hips level.

Dial it down: Skip the leg lifts and hold bridge pose for three counts. Do 10 reps.

Amp it up: Sneak in a few pulses when leg is extended.
