Physical strength and endurance—as well as movement itself—rest on the body’s complex system of muscles. Study the basics of muscle construction and action and the muscular movements in all the key joints. Learn in detail about resistance training and how to construct dynamic workouts around your own fitness goals.

Discover the living structure of the skeleton, the surprising construction and variety of the bones, and how bone health plays a critical role in the quality of your later life. Then, see how resistance training increases bone density, and review the many training options that can delay or even reverse bone deterioration and osteoporosis.

The engineering marvel of the spine provides support for your entire body. Study the anatomy of the spine, spinal motion, and the concept of "core strength"-the action of the spine-related muscles working together. In filmed demonstrations, target the core muscles in exercise, laying the foundation for a healthy back for life.

Drawing on a 3,000-year-old tradition, consider the many proven health benefits of "fitness yoga," which aims to enhance muscular balance and strength, develop flexibility, and improve skeletal posture and lung capacity. In this lecture, demystify the complexities of yoga. Here, you'll practice a sequence of three basic poses and discover how to link them as a routine.

This lecture highlights the remarkable and underappreciated rewards of walking. Track the research documenting the numerous health parameters affected by walking, including its cardiovascular, weight loss, and disease-reduction benefits. Learn the physiology of walking motion, key principles for walking workouts, and three walking techniques you can use to improve your health and fitness.

As one of the core health-related components of fitness, flexibility plays a fundamental role in your quality of life and longevity. Using filmed demonstrations, learn three kinds of stretching techniques (as well as guidelines for your own stretching program) to enhance your range of motion and physical relaxation, reduce risk of injury, and improve posture.
