The video shows a woman lying on a mat on the floor. She is wearing a white tank top and black shorts with a red trim. The woman is performing sit-ups, a common exercise that targets the abdominal muscles. She is lying on her back with her knees bent and her feet flat on the floor. She is holding her head up with her hands and bringing her upper body up towards her knees. The woman is breathing deeply and appears to be focused on her form. The video captures the repetitive motion of the sit-up exercise.
