I started going to Arrichion last fall before their LivingSocial/Groupon deals started going out, and I loved it. The heat, the instructors, the feeling of community - everything.
But then...dun dun dun...the dreaded crowds came. Arrichion puts out so many LS/Groupon deals that the studio has gone from popular and well attended to absolutely-jampacked-unpleasant. Every class I've gone to since the late fall has been totally packed. I've waited outside for 30 minutes and gotten turned away because the class is full (on-line sign ups would be VERY helpful at this gym). Also, there is no instruction in the yoga room whatsoever. The workouts definitely left me sweaty and sore, but the monthly fees are way too expensive for the experience.
Sorry - I was a lover but have moved on.
