In Precision Exercises there are specific exercises to retrain poorly recruited muscles. Once the muscles are recruited well, then there are advanced exercises to strengthen the muscles in a way that reintegrates the target muscle into functional activities.         Precision Exercises is a book by Brian P. Lambert, PT. The book contains "exercises to relieve pain, restore posture, improve balance, and regain control of muscles and movement needed for every day living." The book is designed for use by almost anybody but it is an excellent reference for therapists looking for a systematic approach to exercise prescription. The subjects covered in this book include: basic anatomy and mechanics, beginning and advanced low back and neck exercises, using foam rollers, stretching techniques, advanced abdominal exercises, and upper body exercises with free weights. There are also seven case histories that describe how the exercises may be used with various diagnoses.
