Here is a description of the video: The video shows four people in a gym doing an agility exercise. They are stepping in and out of squares marked on the floor with yellow tape. All are wearing shorts and are barefoot. Three are in the middle of the exercise while the fourth person is standing with his hands on his hips looking at the others. The gym has large windows with a view of a building and the sky. There are weights and other exercise equipment along the walls. The camera is held by a person sitting on a green surface wearing a red shirt.
