Legs and butt: Leap frog

Stand with feet wide apart and toes turned out to 45 degrees. Lower hips down and back to come into a squat (knees behind toes) with thighs parallel to floor; clasp hands in front with fingers intertwined. Keep abs tight, shoulders back, and weight on heels.

Squeeze glutes as you push into heels to spring up (and forward, if room), landing gently in plie squat again; hold 3 seconds, then repeat. Do 15 reps.
