First of all, you don't need to be flexible to do a yoga class and yoga is not about closing your eyes and sitting down, plus although there are some romuor that some people levitates in that position, I have never seen one 😊 My classes usually take 1 hour 15min (£25 per lesson), and all you need is comfortable clothing and yoga mat. Yoga is a miraculous practice and you will get benefits a lot more that you can imagine.
