Move: Stand tall with abs contracted, feet shoulder-width apart. Hold dumbbells, one in each hand, with arms lifted out to sides at shoulder level, bent at elbows, palms facing forward. Push dumbbells straight overhead until arms are extended, pause, rotate palms and forearms to face behind you.
Next, lower dumbbells to chin level, elbows close to your body.
Last, push dumbbells back up―arms extended overhead―rotate palms to front, and lower dumbbells to the starting position.
Repeat: 2 sets of 15 to 25 reps
