A woman in a sports bra and black shorts is performing sit-ups on a blue yoga mat. She is using a semi-circular black cushion under her lower back to aid in the exercise. Her hands are clasped behind her head, and she is lifting her upper body off the ground. She has a ponytail. The exercise mat sits on a floor inside of a gym. Behind her are treadmills, with people walking on them. In the distance are other pieces of exercise equipment and other people.
