We’ve all heard of yoga. It has been around for more than 5000 years. Some of us have even taken classes (okay, one class –I’m kind of flexibility-challenged). Many health experts believe that practicing yoga is a good way to stay healthy. The stretches and poses of yoga build a strong core, improve posture, lower blood pressure and even relieve stress. According to WebMD, yoga has been used to successfully alleviate the symptoms of asthma, back pain and insomnia among other common ailments. Sounds great, right? But before you decide yoga just can’t sound any better, consider doga.
