The video shows a young boy on a treadmill, holding a pink dumbbell in one hand. He is wearing a gray shirt with a dinosaur print, green shorts, socks with dark stripes, and dark sandals. The boy stands near the front of the treadmill, his left hand resting on the machine's support bar, and alternates raising both arms to shoulder height. The treadmill is silver and gray with a digital display showing red numbers. Through a window in the background, another person is visible, partially obscured. The environment appears to be a gym, with other exercise equipment visible nearby. The wall behind the treadmill is off-white.
