Calisthenics and mobility training are proven to develop strength and agility without the risk of injury, and with the tips, advice, and exercises provided in this book, anyone can become strong and supple. This practice-oriented guide goes far beyond the dry technical literature on proper strength training. The authors have combined the best strength-training methods with modern mobility training, meaning the reader will become strong through pull-ups, push-ups, and dips while remaining supple with active stretching. With mobility training, there will be no need for painful foam-rolling or dull stretching exercises. Instead, the reader will focus on movement and range of motion. Better mobility means more strength and combining these two aspects of training will lead to the best and fittest version of one's self.
