If your asking yourself how important is a daily yoga practice, I would tell you that there is no definitive answer to this. You should know that yoga is a good physical exercise and can help increase your fitness level. It as been proven that exercising regularly increases the amount of endorphin in your brain. Endorphin is like a drug: it makes you feel good and its addictive. So this means it can affect your mood in a positive way and make you an addict of physical activity which is great.
What yoga provides that you may not find in other activities is the spiritual side of it. This can provide even better relaxation and stress control. Did you know that stress is one of the major cause of death in North-America?
So the question being “how important is a daily yoga practice?”, I would have to say it’s not about doing it daily but more about doing it regularly (2 to 3 times a week). I know many people that practice yoga only one time a week and still experience a great deal of satisfaction out of it. What you should consider if possible is practicing yoga once a week and than practice your favorite physical activity 2 more times a week. This will provide a great workout routine which will greatly benefit you.
