I've been practicing yoga for 7 years now and as a new resident in the Valley was looking for the best places to deepen my practice and committment to yoga. My first classes with Yoga Nirvana where the community ones with Amanda Manfredi ($5 per class). That was amazing, I really respected the way Amanda used to teach and practice yoga, that made we continue going to her classes until she left to San Diego. After that, I decided to get a pass at the studio and currently going to Jim's level 2 flow class. I absolutely enjoy every single drop of sweat. The atmosphere is very relaxing, nothing of that pretentiousness that abounds in most of the studios; a combination of great challenging classes with the meditative practice of the breathe as a mean for the cultivation of the soul. I personally think that adjustments are an essential part of the practice and Jim does it great. I still haven't try the rest of the instructors, though.
The studio is inexpensive and offers student's discount and all packages. I would greatly recommend it. At least give it a try!!
