Yoga enthusiasts practice various yoga traditions, all of which combine forms of breathing, posture and exercise. Asanas are isometric moves that stretch and strengthen muscles. Yoga strengthens muscles by incorporating resistant weight-bearing exercise, using the body's own weight as the resistance. Yoga helps stretch and tone muscles, and can improve posture and increase muscle endurance. Many studies also suggest that the stretching postures of yoga can reduce stress, prevent injuries, speed up injury recovery and relieve back and neck pain.
Proponents also credit yoga with providing a deeper sense of well being.
If you aren't interested in trying a new exercise, there are other ways to become more motivated about your current workout. Make a workout tape of your favorite upbeat songs. Music can be a great motivator. Find an exercise partner. It's harder to skip a workout when you know someone is counting on you being there.
