In the video, a woman is seen performing a side plank exercise on a blue yoga mat. She is wearing a white long-sleeved shirt and black leggings. The woman starts in a plank position with her left arm extended upwards and her right arm extended downwards. She then brings her right arm up towards her chest while keeping her left arm extended upwards. She repeats this movement several times, alternating between extending her right arm upwards and downwards. The background is a plain white wall with a rack of colorful exercise balls.
