IF YOU ONLY BUY ONE BOOK ABOUT TENNIS-SPECIFIC TENNIS TRAINING, THIS IS THE BOOK YOU SHOULD BUY! The best resource for tennis specific fitness. Amazing! This book is written by a qualified sports scientist and contains absolutely everything you need to plan and carry out effective training programs with tennis players of any age, level and ability. The book uses sports science jargon and terminology, which may be a bit 'heavy' for those with a non-sports science background. I'm a personal trainer, so I understand. However, it is written in a clear and concise style with effective illustrations. Covers areas such as energy sources, flexibility, proper warm up/ccol down, nutrition, resistance and cardiovascular training, speed/agility/quickness, physical testing and periodisation superbly. The USTA Conditioning for tennis by Roetert and Ellenbecker is also an excellent resource and perhaps easier to follow for people without a sports science background. It comes with a DVD with excellent drills eg. dynamic warm up, fitness tests, resistance training etc. Avoid the SAQ conditioning for tennis book (with Roddick on the front cover) Its training methods are very dated. AVOID AVOID! I've played tennis for 13 years (I'm 21) and a qualified personal trainer, so you can trust my judgement. This book was recommended to me a friend, who did a Masters degree in Sports Science. His Masters degree was on tennis movement, so he knows what he is talking about. He was spot on!
