Fifteen hours tennis training for two tennis families from Singapore went well. Two boys, Jerome aged 9 and Thaddeus aged 10 practiced for an intensive fifteen hours over just three days. On the first day they could not play in the evening session due to rain, so they trained for seven hours on the last day. This challenged both boys. It was especially tough for Thaddeus but with encouragement from Jerome, he pushed through his tears until they both finally accomplished their training program. Over the course of the lessons, Jerome noticeably improved his technique with different strokes and Thaddeus learnt to use less power. His game improved when he started to relax. Both boys followed instructions well.
