Do I really have to sweat? Do I have to deprive myself? Do I have to do yoga?
Yes! Yes you do. Aim for 30 minutes 5 x week.
No! No you don't have to deprive yourself of healthy, fresh foods. It's all a balance, so aim for sticking with the 80/20 rule.
Sometimes...Sometimes you do need to get on a yoga mat, and the more time you do the more your mind and body will thank you.
