Performing the: A Step-by-Step Tutorial Dumbbell Full Can Lateral Raise
Keep your arms slightly bent at the elbows and your back straight, then slowly lift the weights out to the sides until they are level with your shoulders.
At the top of the movement, your arms should be parallel to the floor and your palms should still be facing forward, like you're pouring out two cans of soda.
Pause for a second at the top of the movement to really feel the contraction in your shoulder muscles.
Slowly lower the dumbbells back down to your sides, maintaining control of the weights as you do so, and repeat for the desired number of repetitions.
