Physical conditioning literally changes you on the inside. It strengthens your belief in yourself and what you can do. It fills the hole created by insecurity. By working on your outside Body, you can actually alter your inside physiology, change your Brain chemistry, and change your outlook on life. . . and on yourself. In this transformative book, Work Out reminds us that the human existence is physical, and when you train your Body from the outside in, rather than from the inside out, profound changes occur to your Brain, which stimulate your Mind and your approach to life.
