A woman is seated cross-legged on a black yoga mat on a light wooden floor, against a plain white wall with a white grid-tiled ceiling above. She is wearing a black long-sleeved athletic top with a quarter-zip, black shorts, and a black headband. She is holding a long yellow resistance band. The woman demonstrates an exercise focused on breathing and chest expansion. Initially, she positions the resistance band around her torso, just below her chest, holding one end in each hand. She then inhales deeply, expanding her rib cage against the band, which stretches it horizontally. Her shoulders remain relaxed, and her gaze is directed forward or slightly upwards. She holds this expanded position briefly before exhaling and relaxing her chest, allowing the band to return to its original tension. This action is repeated, emphasizing controlled, deep breathing to engage the respiratory muscles and stretch the chest. The woman maintains a calm and focused expression throughout the exercise. The setting suggests an indoor exercise environment, possibly a home or studio in Votkinsk, Russia.
