Train like a pro! Yellow ball development tennis coaching uses full-size courts and the classic yellow tennis balls you see flying through the air at Wimbledon. Aimed at players who are physically or technically able to learn at the full pace of a real tennis match, our Thrive Performance programme is an exciting stage where players begin to develop noticeable skill and tactical awareness. It is a natural progression for those who have attended Mini Tennis coaching programmes, but can also be a friendly and fun introduction to the sport for those who haven't had a chance to pick up a racket yet.
