Crossbox

In a gym with a "CROSSBOX BAND" sign, a man in a black tank top and a woman in a neon yellow shirt perform a synchronized exercise, jumping onto a wooden box while simultaneously throwing and catching medicine balls above their heads. The man jumps onto the box, catches the ball, and throws it upward, while the woman jumps onto the box, catches the ball, and throws it upward, repeating the sequence in a continuous loop.
