Performing the: A Step-by-Step Tutorial Dumbbell Rear Lateral Raise
Lean your torso forward slightly, bending at the hips, while keeping your back straight. Your palms should be facing towards your torso, and your arms should be hanging in front of you.
Keeping a slight bend in your elbows, lift the dumbbells out to your sides and upwards until they're at shoulder level, focusing on squeezing your shoulder blades together.
Hold this position for a moment, ensuring you're using your rear deltoids to lift the weights and not your back or neck.
Slowly lower the dumbbells back to the starting position, controlling the movement and not letting the weights simply drop. This is one repetition. Repeat for the desired number of reps.
