http://tennisdrillshq.com/drills/private-lessons-1-player/follow-the-coach/ - In this tennis drill the coach will move laterally side-to-side, staying at a certain location for a certain amount of shots that is up to the coach’s discretion. The coach will then move laterally to another position for the player to continue to hit back to. The coach should volley balls back to the player and move them around the court.
