Extend the arm holding the dumbbell straight above your head, keeping your elbow close to your ear.
Slowly bend your elbow, lowering the dumbbell behind your head until your arm forms a 90-degree angle.
Pause for a moment, then extend your arm back to the starting position, ensuring to keep your elbow stationary and close to your ear throughout the movement.
Repeat this exercise for the desired number of repetitions, then switch to the other arm.
Pro Tip
Controlled Movement: Extend your arm upward, raising the dumbbell until your arm is fully extended. Make sure the movement is slow and controlled. Avoid jerking or using momentum to lift the weight, which can lead to muscle strain or injury. Keep Your Core Engaged: As you perform the exercise, keep your core muscles engaged. This will help maintain stability and balance, preventing unwanted movements that could affect your form or lead to injury. Don't Lock Your Elbows: While it's important to fully extend your arm, avoid locking your elbows at the top of the movement. This puts unnecessary stress on the joint and can lead to injury
