A shoulder stand in gymnastics is a position where the gymnast balances on their shoulders with their legs extended vertically upward. The hands can support the lower back for stability, showcasing balance and core strength. To perform a shoulder stand, start by lying flat on your back with arms at your sides. Lift your legs straight up towards the ceiling and support your lower back with your hands, elbows resting on the floor. Raise your hips off the ground to achieve a vertical position supported by your shoulders, ensuring your body forms a straight line from shoulders to feet.
