A woman in a blue leotard is performing a Pilates exercise on a reformer machine. She is lying on her back with her feet in straps attached to the footbar. She is extending her legs out in front of her and then bending her knees to bring them towards her chest. The reformer machine is made of wood and has springs and ropes. The room is well-lit with natural light coming from a window. There are plants and furniture in the background.
