Outside Practice

I went to the Yoga Technique class I really like going to these because it allows me to correct the posture because they are held for a longer period of time. Lately when I have been practicing I am waking up a little sore the next day. I would really like to start practicing everyday, but I have a crazy schedule so it is hard for me to find time to get to the studio everyday. I noticed that there are a lot mixed ages in this class also. I feel like a lot of the older men and women are there for therapeutic reasons and that a lot of them have an illness or arthritis and are trying this as a method for treatment. I mean I could be totally wrong but that is what I am starting to observe.
