An outdoor calisthenics park in Borisova Gradina Park, Sofia, Bulgaria, is depicted under an overcast sky. A muscular, shirtless male with short hair is positioned in the foreground, performing a one-arm push-up or pseudo-planche push-up variant. He balances on his right hand, with his body nearly horizontal to the ground and his left arm bent and off the surface. He wears grey sweatpants and black athletic shoes, with his legs extended straight backward. The exercise area consists of dark green square rubber tiles. To the left, a black and orange "NATRIT" branded calisthenics structure features vertical ladders with seven visible orange rungs, showing some wear. To the right and behind the individual, another section of the black "NATRIT" structure includes a horizontal bar with two gymnastic rings. Beyond the equipment, a grassy area with bare deciduous trees is visible, along with an asphalt path, a low red metal fence, and a discarded wooden pallet. In the distant background, urban elements include parked cars and multi-story buildings.
