Yes, a consistent yoga practice can help you increase flexibility and strengthen your core. No, you do not need to lose fat before starting a yoga practice. I would suggest that you begin by attending classes (as opposed to doing yoga with a DVD), because a teacher can help you modify any poses that you find difficult, until you become more flexible. If attending classes sounds a little intimidating, look for a teacher that will schedule a private session with you, and help you come up with a routine that you can do on your own at home.
My yoga teachers have said it’s important to ‘start where you are’ and move forward from there!
No, you don’t need to wait… because, simply if you don’t start now yoga, you’ll never get in your shape and boost your energy level. So, no matter how your actual shape is, I advice you to start. Learn yoga poses, how to do them, their physiological benefits and the deep breathing techniques as well… You can get this free yoga e-course for your benefits:
