Performing the: A Step-by-Step Tutorial Dumbbell External Rotation
Bend your elbow at a 90-degree angle and keep it close to your body, with your forearm parallel to the floor and your palm facing inward.
Slowly rotate your forearm outward, away from your body, lifting the dumbbell as far as you can while keeping your elbow and upper arm stationary.
Hold this position for a few seconds to engage your shoulder muscles.
Slowly lower the dumbbell back to the starting position, ensuring you maintain control throughout the movement. Repeat the exercise for the desired number of reps before switching to the other arm.
