For PIKABU

In a dormitory with bunk beds, a shirtless man in green shorts stands with a blue resistance band around his thighs, then turns and walks away from the camera, revealing a red resistance band around his knees and a black resistance band around his waist. He walks toward the back of the room, where another man sits on a lower bunk, while a third man sits on a bed in the foreground, and a fourth man is visible in the background.
