young woman with long, dark hair taking a mirror selfie in a brightly lit gym. She is wearing a white sports bra and black leggings. Her left arm is bent at the elbow, and she is holding a blue handheld exercise device with her left hand. A purple scrunchie is around her left wrist. She has a tattoo on her left arm. In the background, another woman is visible using gym equipment, and a man with curly hair is also present. A large black piece of gym equipment with the word "MATRIX" vertically printed on it is to the right of the woman. The gym has wooden flooring and yellow and grey walls with inspirational text visible on one wall. The overall environment suggests a modern fitness facility, likely in Sofia, Bulgaria, based on the context.
