In the video, a woman is seen sitting on a yoga mat in a room with a concrete floor and walls. She is wearing a neon green sports bra and black shorts. The woman is performing sit-ups, starting in a seated position and then lifting her upper body towards her knees. She repeats this motion several times, demonstrating good form and control. The room is well-lit with natural light coming in from the windows, and there are no other objects or people visible in the frame.
