"Jumping Jacks" is a video demonstrating a classic aerobic exercise that involves jumping from a standing position while simultaneously spreading the legs wide and raising the arms overhead, then returning to the starting position with the legs together and arms by the sides. This exercise is effective for warming up the body, increasing heart rate, improving cardiovascular endurance, and engaging muscles throughout the body, including the legs, core, and shoulders. The video typically focuses on proper form, pace, variations, and the benefits of incorporating jumping jacks into a fitness routine for overall conditioning and calorie burning.
