Arm Rotation is a fundamental movement that involves rotating the arm at the shoulder joint, extending from the center of the body to the hand. It is a basic skill that is essential for many daily activities and athletic pursuits. To perform an effective arm rotation, start by standing or sitting with your feet shoulder-width apart and your arms at your sides. From this position, slowly lift one arm out to the side until it is parallel to the ground, keeping your elbow straight and your palm facing downwards. Next, rotate your arm in a smooth, controlled motion, moving your hand in a circle around your body. Continue rotating your arm for several repetitions, then switch to the other arm and repeat the process.
