The video shows three people working out in a gym. They are lying on their backs on a green turf floor, with their legs bent and feet resting on blue plastic chairs. They are performing a core exercise, raising their legs and lower back off the ground simultaneously. There is a kettlebell, weight plates, a treadmill, and a stationary bike in the background. One person wears khaki sneakers and black socks, another wears black socks, and the third has white socks.
