Pilates body conditioning is today's fitness buzzword, and following the storming success of Lynne Robinson and Gordon Thomson's original "Body The Pilates Way", a variety of books have appeared - none as authoritative, practical, safe and geared towards solving your body's problems as this. 'How will Pilates help me?' is its keynote, so after explaining the fundamental Eight Principles through accessible, balanced core programmes come 'Pilates prescriptions' for your specific needs. With the growing support of many GPs, osteopaths and chiropractors, not to mention stars from screen, stage and sport, when you exercise with "Pilates Body Control", you're in excellent company. From back pains, posture problems to prevention of common sports injuries and training your children to use their bodies properly, this is the one-stop reference.
If you are thinking a little core conditioning might be in order, this is a great book to start. It has a section on principals beginners, intermediate and advanced. I then has a section where you can see which exercises fit your job or your activities. Clear pictures and explanations. I got this a few years ago and just re-read it.
This is a great reference for isolating target muscle groups. Point specific for foot/knee/back you name it they have an exercise workout set up for it.
