Teaching chair yoga at the local senior center began as part of my final project (the Seva Workshop) when I was taking a course to expand my teacher training to a 500 hour certification.  The experience was very inspiring and I've been volunteering every other week since!  The class is geared towards seniors of different mobility ranges, but definitely will feel good for most anyone.  This summer I started posting my classes on YouTube to help benefit more people - they can be found here.  I'm hoping to gain 500 subscribers so I can take out the ads YouTube places in the middle of the class.  They can be disruptive to the flow!  I'm just over halfway there.
