A woman is performing a workout on an exercise mat. She is on her hands and knees, with her hands positioned under her shoulders and her knees bent. Her body is in a plank position. She then twists her torso to the side, raising one arm towards the ceiling, and then returns to the starting position. She repeats this movement on the other side. The background of the video shows a wall with a large artistic mural depicting a human skeleton. There are also dumbbells visible on the mat.
