It's a quaint and quiet little studio in Verdun where they have Yoga, acrobatic yoga and even Systema martial arts classes. The people who run the place are friendly and very nice.
I went there because I was given a pack of courses as a gift. The only time I could go was on Wednesday evening and that's when they have the Yoga Foundations classes. The type of yoga was challenging and quite frankly, was awkward at times. We were instructed to build complex setups with blocks and chairs and cushions on top of which we had to lie and keep a difficult pose for a long period. Everyone had trouble getting set up and we spent more time getting ready than doing the actual poses. Finally, everyone ended up having numb legs and feet and our knees would hurt from sitting on our knees for too long. And often, the postures using the chairs left us with a lot of back an neck pain. Especially those where we had to do awkward inversions. I am very sceptical about how beneficial that was as the next day my spine would hurt in a couple of areas and a bad headache from the muscle pain in my shoulders and neck.
I don't know about the other classes, but I wouldn't recommend doing the Yoga Foundations classes, especially if you have back problems.
Other than that, like I said, I've only attended that one kind of class so I can't say what the other ones are like. And the people were nice too.
