Something that's not always broadcasted at yoga studios is that if you wanted to get more involved and attend more classes at a particular studio for free or at a discounted rate -- it's common for studios to offer work exchange programs. Basically, you would clean or run the front desk for a couple of hours a week in exchange for free yoga or a discounted unlimited pass (the exchange varies studio to studio). It's a really good option for people that face financial challenges but would love to maintain a practice at a certain place. 

A couple of places in Denver / Boulder that I found offer this option are: CorePower Yoga, Yoga Pod, One Yoga Denver, and Denver Bikram Yoga

If you think someone you know would like this option, please pass this on.
