The player kneels down and and blocks resistance band using left hand. The player takes straight dominant arm up to the shoulder level and comes back. The player also should maintain a straight back.
In this drill, the player works on strengthening shoulder muscles. Many injuries in tennis are related to dominant shoulder because faster pace of the game and many serves put a lot of stress on this area. Young players tend to hit backhand volley using 2 hands because they don't have enough strength to perform this stroke with one. This exercise prevents shoulder injuries as it also prepares players to be able to hit backhand volley/slice in the near future.
Indoor courts give players less time and less room. Help them sharpen their split step, shorten their swing and stay calm, and winter becomes a season of real progress.

Most club players practise the serve on its own and then have no idea what to do with the ball that comes back. Serve plus one is the pattern that turns a good serve into a won point.
