A friend suggested Pilates as a simple form of exercise that could be done from home, keeping it straightforward and cost effective. This book does everything it says on the tin, so to speak. As I am over 60 and overweight I've lost my flexibility and this book has begun to bring some movement back. There are specific sections that deal with individual sports and as an ex hockey player and swimmer they are very useful and give you a regime that works , rather than aimlessly going through the pages. I would recommend this book to any person of my age or older but also wish I'd have seen it earlier , in mt 50's as it would have kept my fitness level up.
