I've been going to Moksha Yoga on & off for years. I've been to the Hwy 7 location and the Hamilton location (University Plaza).
As far as hot yoga studios go, I've yet to find one better.
- The basic classes (Moksha Flow & Moksha 60) are genuinely challenging, but are still accessible to beginners. (FYI my background is full of various athletics and I workout regularly, often daily.)
- There's a tone of variety for what classes they offer, especially if you're looking for a bit more of a challenge
- The instruction tends to be great
I can go on for a while, but I love this place, (or at least the locations that I've been to).
One down side; it's not cheap! I guess you pay for what you get... Try it out!
