Performing the: A Step-by-Step Tutorial Dumbbell W press
Bend your elbows at a 90-degree angle, so that your upper arms are parallel to the floor, and your forearms are pointing straight up, dumbbells above your head.
Open your arms out to the sides, creating a W shape with your body and arms, keeping the elbows bent and the dumbbells at the top.
Hold for a moment in this position, then bring your arms back together, returning to the starting position.
Repeat this movement for the desired number of repetitions, maintaining the W shape throughout the exercise.
