Set up for the exercise by getting an adjustable angle bench and setting the back to 90 degrees.
Use your thighs to help you raise the dumbbells to shoulder height on each side, and twist so that your palms are facing your body. The dumbbells should now be positioned directly in front of your shoulders.
Your back should be flat against the back rest and your feet firmly planted on the floor for stability. This is the starting position for the exercise.
Keeping your eyes facing forwards, slowly raise the dumbbells while turning your wrist so that your palm is now facing forward (away from your body).
Keep raising the weight until your arm is almost fully extended. Begin lowering the dumbbell back down to the starting position - twisting at the wrist until your palm is facing your body once again.
