Newly revised for 2020! See inside every stretch as you increase flexibility and improve muscular strength. Expanded, enhanced, and updated, this best-selling course shows you how to increase range of motion, supplement training, enhance recovery, and maximize efficiency of movement: it is like having an X-ray of each stretch, only better. Not only do you see full-color illustrations of the muscles in action, but you also see how a change in position can alter the muscle emphasis. Each exercise describes how to stretch, when to stretch, primary and secondary muscle emphasis, and which muscles are activated for support. Stretching programs provide three levels of difficulty, including light stretching that can be used to aid in recovery from soreness and injury. Course includes soft-cover textbook, separate testing booklet and free, instant grading. Softcover, 232 pages.
