In the video, a woman is seen performing sit-ups on a mat. She is wearing a yellow sports bra and black leggings. The woman is in a gym, and there is a large window in the background. She starts by lying on her back and then lifts her upper body off the mat, bringing her knees towards her chest. She then lowers her body back down to the mat and repeats the motion several times. The woman appears to be focused and determined as she completes her exercise routine.
