Our muscles can tighten up if we dont stretch enough before or after training, from playing to many overhead sports, such as tennis, volleyball, baseball, and swimming and from sitting behind a desk for long periods of time. Tight muscles can limit your range of motion and cause pain and poor posture. Are your muscles tight? The exercises in this book will help to loosen those tight muscles, stabilize your muscles, relieve pain, improve your posture, increase your range of motion, decrease the risk of injuries, and strains when you work out. | Mobility Exercises by Jason Downie, Paperback | Indigo Chapters
