A woman is performing core exercises on a gray yoga mat in an indoor gym. She is wearing a light purple long-sleeved top, light gray sweatpants, and blue and white athletic shoes. She is holding a light blue yoga block above her head with both hands, raising her torso and legs simultaneously before lowering back to the mat. Her expression shows concentration. In the background, a man is seen exercising on a piece of gym equipment, possibly a hyperextension bench, with his back to the camera. He is wearing a red t-shirt. The gym features a light wooden floor, a brick-patterned pillar, and glass partitions. A sign on the wall to the left clearly displays the word "ТЕННИС" (TENNIS). The yoga mat has the brand "CUNFIT" visible on it. The setting appears to be a well-lit fitness center during the daytime, with an active atmosphere.
