Here's how to do it with good form. Stand with feet
shoulder-width apart, then bend knees and flex forward at the hips. (If you
have trouble doing this exercise standing up, support your weight by sitting on
an incline bench, facing backward.) Tilt your pelvis slightly forward, engage
the abdominals, and extend your upper spine to add support. Hold dumbbells or
barbell beneath the shoulders with hands about shoulder-width apart. Flex your
elbows, and lift both hands toward the sides of your body. Pause, then slowly
lower hands to the starting position. (Beginners should perform the move
without weights.)
