1. Stand upright with your feet shoulder-width apart and your arms by your sides.
2. Engage your core and maintain a straight posture throughout the exercise.
3. Without bending your elbows, lift your arms directly out to your sides until they are parallel to the floor. Try to keep your palms facing downward as you raise your arms.
4. Once at the top position, quickly flip your palms to face up towards the ceiling without lowering your arms.
5. Then, quickly flip the palms back to face down while still keeping your arms elevated.
6. Lower your arms back to the starting position by your sides in a controlled movement.
7. Repeat the raise and palm switching for the desired number of repetitions and sets.
This exercise helps to improve shoulder strength and stability. It's important to move in a controlled manner to prevent momentum from taking over the movement, and to keep the focus on the deltoid muscles. The switching of the palms mid-air adds an additional element to challenge your coordination and proprioception.
