Single Arm Dumbbell Z Press

Instructions for proper form

Sit on the floor with your legs extended in front of you and feet flat on the ground. Hold a dumbbell in one hand with a neutral grip, raising it to shoulder height. Engage your core and keep your back straight. Press the dumbbell overhead, maintaining a straight line from the wrist to your shoulder. Lower the dumbbell back to shoulder height with control. Repeat for the desired repetitions before switching arms.

Common mistakes to avoid

Avoid arching your back or leaning excessively to one side. Do not let the dumbbell drift forward or backward; it should remain aligned over your shoulder. Ensure you are not using momentum to lift the weight; the movement should be controlled and deliberate.
