I love Bliss Flow.
For years I've been interested in starting a yoga practice but could never seem to get into it. I was ready to determine it as just not my thing. I disliked (and still dislike) the misappropriation of a culture at some places that do chants and meditation.
I bought one of the Groupon deals and was certain that I'd only do a couple of sessions rather than the whole 20, but Bliss Flow has converted me and I bought several more class passes after that.
I find that my experience at Bliss Flow depends a lot on the instructor. Some of the instructors do a ton of flows whereas I prefer a variety of poses and holding the poses for longer. I once left a class in the middle simply because I didn't enjoy the instructor at all. However, with some of the better instructors, I found that switching between their classes helped challenge me.
Some of the classes can get very crowded, especially the Happy Hour Yoga. I prefer the morning classes which have about 20-30 people. Not too small, but not too huge, and plenty of space to spread out in the studio. I prefer the instructors to not be super hands on with adjustments. I prefer them to correct things that may cause injuries, but otherwise, I like that they encourage it to be my own practice and for me to do what feels right at that moment.
