This image depicts an indoor athletic facility located in Varna, Bulgaria. In the foreground, a large black mesh safety net, with square openings, extends across the frame. This net is attached to a red-wrapped vertical support pole on the left and a red-wrapped horizontal bar along the top. Behind the net, a female individual, appearing young adult, is positioned in a semi-reclined posture on a stack of at least eight blue rectangular padded mats. She is dressed in a black hooded jacket, black pants, and black athletic shoes with white soles. Her left hand holds a white-cased smartphone, which displays "12:00" on its screen. Her right leg is bent and elevated, with her right hand grasping her lower right leg. The facility's floor is covered with blue matting, featuring a black line running horizontally in the mid-ground. The background consists of light-colored, paneled walls. To the right of the individual, a white-framed rectangular opening is visible in the wall, revealing a red vertical element within its interior. Adjacent to this, a smaller, vertically oriented rectangular opening is also present in the wall.
