Exercise Vs Yoga

Exercise Vs Yoga

   I always inquired myself the difference between yoga and Exercises. Recently i have gone through an article from a news magazine. In that i clearly understood the differences. The glimpse of it is here 
1. Exercise is catabolic which is capable of breaking down the energy
    Yoga is anabolic which conserve energy
2. Exercise is sympathetic stimulation
    Yoga is parasympathetic simulation
3. Yoga is always used as relaxation technique where this not same for exercise
4. Yoga always improves the blood circulation to Visceral organs like spleen, liver, kidney. Yoga uses breathing technique which squeezes the organs to increase the blood circulation. In yoga blood supply to the muscle is not increased.
    Exercises focuses on the muscular system that gets 70% of the blood supply.
