Valerie Hockert is a certified personal trainer and nutritional consultant. She found that exercise can help reverse the aging process, so has continued to exercise throughout her life. Although as one gets older, one can put less emphasis on cardio and more emphasis on stretching and toning. This book is all you need to have a great exercise program. Some of the exercises are seen in yoga and Pilates classes, as well as physical therapy classes, so if you are one who has aches and pains (for example, neck, shoulder, knee or back pain), this book will be very beneficial to you. Exercise plays an essential role in developing a healthy, well-toned body. The Whole Body Tone Up Book, with over 100 exercises, provides a complete, highly effective exercise program that will not only make you feel better physically, but mentally and emotionally as well. You may choose to follow the entire program, or use the unique "crash course" of basic exercises when you are short of time. If you have problem areas that you want to trim down and tone up, special chapters concentrate on improving the waist, thighs, stomach and back. Exercise does take determination, but with the clear illustrations and directions, you will find it easy to follow the beneficial exercise programs in The Whole Body Tone Up Book. Have a great workout. Combine your workout with a good healthy diet for optimum results.
