Here’s a description of the video: A man practices his tennis serve on an indoor court. He is wearing a white t-shirt, black shorts, white compression leggings, and athletic shoes. The tennis racket he is using is black and red. The court has green flooring, with a blue section to one side. There is green netting in the background with a Babolat logo. He throws the tennis ball upward and swings the racket. He catches the ball after his practice swing.
