Hulk Optimist

A shirtless man in a locker room pulls on a locker door, then appears in a light blue jersey, throwing a small object at a door handle. The scene cuts to an outdoor training area where two men in matching jerseys perform a football trick on a seesaw-like contraption, one kicking the ball while the other balances on the opposite end. The sequence ends with the man in the jersey standing in a room, smiling after the throw.
