It's getting closer and closer to shorts, skirts and beachwear. Target those hard to get areas (hips and butt).
Stand with your feet hip-width apart, arms reaching forward at the shoulder level, palms facing each other.
Lift the right leg behind you as high as possible, toes pointed (unless you cramp, flex your feet instead), leaning forward slightly.
Lower the right leg toward the floor without touching and repeat the lift.
Do 10 reps. Switch legs and repeat. Do 2 sets on each leg.
Make it harder: Do 10 pulses at the top of every leg lift!
