The video features a woman in a pink tank top and black leggings demonstrating how to do a proper jumping jack. She starts by standing in front of a row of gym equipment, including treadmills and weight machines. She then proceeds to perform the jumping jack, starting with her feet shoulder-width apart and her hands by her sides. She then jumps up, bringing her knees to her chest and her hands above her head, before returning to the starting position. Throughout the video, she speaks to the camera, providing instructions and tips on how to perform the exercise correctly.
