An old, but nevertheless excellent, resource on strength and conditioning methods is Judo:Training Methods by Donn Draeger and Takashiko Ishikawa.I regularly use drill that can be found in this book to warm-up the class and condition them. One of the beautiful features of the exercises and drill is that they directly relate to Judo techniques and situations. Judo is a fine martial art, a living martial art, and an art that marries form and function.
Many of the drills in this book have been appropriated by other arts, such as Brazilian Jiu Jutsu. This is an excellent primer on basic conditioning methods. Certainly there have been advances in fitness since the 1950's when this was written. A wise student would seek out the latest information. However, it seems to me that "what's old is new again" in many instances with fitness. Consider, for instance the resurgence of Medicine Balls and kettlebells. Perhaps more martial artists should check into this book for insight.
