I think that is going to depend on how often you go. If you only go once in the month, that's pretty steep. If you go three times a week or more often, it's probably a pretty good deal!
Thanks guys, and yeah I think that's a great deal. Not like other vigorous exercises, yoga can be done as often as you want. Well, I mean you can do it twice a day (in the morning and in the evening).
That's $1200 a year. It seems a bit steep to me, but if it serves as a good preventative measure, then it is money well spent. Beats the heck out of doctor bills.
