Training sessions
During a typical training session children will not just be learning tennis skills.
The court is split up into sections and every child does an activity that develops different areas of their athleticism.
According to Steve Amos, who's the County Mini Tennis coach for the Lawn Tennis Association in Nottinghamshire, a child can develop co-ordination up to the age of 12, but after that it becomes a lot harder.
Awards and competiitons
From September 2002 mini tennis will have its own awards system.
Children will be able to gain stickers for completing various sections of the course which they can then stick on an award card.
