I tried several yoga studios in NYC and after attending many clases during their two week ($30) trial, I would not go back. Some of their teachers do have an odd hostile attitude and the aura is that of coldness, starkness and almost a corporate gym mentality. Much of the spiritual elements of yoga are missing here greatly. During one class, we did some kind of weird backbend over a metal chair. The teacher demoed it and we repeated. Imagine being upside down over a metal chair. I couldn't figure out where to put my hands exactly - it is difficult to feel when you can not see and are upside down. The teacher rebuked me like a child and asked obnoxiously, "Did you even pay attention during the demo?" Very nice *karmic* approach. Namaste? Teachers contradict each other - in other words, there is no unified approach and philosophy. One teacher had us doing headstands with a blanket and our hands shoulder width apart flat on the floor, and another teacher in another class asked me almost mockingly where I learned to do a headstand like that and told me a blanket makes the surface uneven and my hands should be crowned around my head. It just seemed like instead of yoga balance, focus and warm positivity, yoga works is about something entirely different and full of negativity and a very un-zen approach. I joined another studio and still get calls and messages left on my voicemail trying to get me to join here.
The only positive things: Their changing room on the UWS location is beautiful, clean and has locking lockers so you don't need a lock. (The other lcoations were not such) Their monthly deal was pretty good pricewise - when I was there, it was $85 a month for one studio or $115 to use all 4 locations unlimited. They said it might go up $5 soon but that is still better than most other studios in NYC.
Still, good price and deluxe changing rooms are definitely, definitely not the only factors in choosing a place to practice - keep in mind.
Pros: Good monthly deal, many classes in 4 locations can be convenient
Cons: Everything else
