Stand up straight with feet at shoulder-width apart, hold one dumbbell in each hand, raise two dumbbells to head height, elbows out and 90 degree, forearms should be perpendicular to the floor, palms facing each other. That is your starting position
Extend through your elbows to raise two dumbbells together until they touch at the top
Then, slowly lower the dumbbells back together to the starting position
Breathe out when raising and in when lowering
Tips:
Keep your upper body and legs stationary during the whole process, and do not jerk your upper body or use leg-drive to help you raise the dumbbells
