Ever try to do yoga?  It’s not easy lifting yourself off of the ground while attempting to stretch your leg around your neck at the same time.  You must be totally concentrated and extremely flexible.  It takes time to achieve many of the classic yoga poses.  Some people are fanatical about being able to achieve them.  Yoga, as we all know, is very relaxing but if you plan on doing some, make sure you don’t have any broken bones or bruised muscles because you can harm yourself.  Take your time and go slow and most of all, have fun.
