A first-person point of view video shows a person performing leg extensions on a gym machine. The person is wearing black leggings, grey and neon green athletic shoes, and what appear to be matching knee sleeves or socks. Their legs are positioned under black padded rollers, which they push upwards as part of the exercise, with a yellow adjustment knob visible on the machine. In the background, two treadmills are visible. One treadmill has a person walking on it, while the other is empty. Both treadmills have "AeroFit" text visible on their sides. The gym floor is dark grey. The overall setting is an indoor fitness center or gym.
