In the video, a woman is seen holding a large yellow and gray exercise ball. She is wearing a blue shirt and black pants. The woman then proceeds to perform a mountain climber exercise on a black mat. The exercise involves placing one hand on the ball and the other on the ground, and then alternately bringing each knee towards the chest while keeping the body in a plank position. The woman repeats this motion several times. The video is shot in a well-lit room with a plain background.
