Long before weight machines, stationary bikes, and step aerobics became tools in any weight-management plan, people practiced yoga for spiritual and physical health. The origins of yoga predates written history. Archeologists have uncovered stone carvings depicting figures in yoga positions in the Indus Valley dating back 5,000 years or more! While it might not produce the rapid results that fast-paced aerobic exercises or high-tech weight machines do, yoga still has plenty to contribute to your weight loss program in the 21st century.
