I'm guess I'm spoiled. I'm used to Mission Cliffs in San Francisco, where a ~$65/month membership got you climbing, cardio, weights, along with spin, kickboxing, and yoga classes.

Honestly, though, I do think the fairly standard $15 per session is way, way too much for yoga. $15 per head with a class size of around 20 is $300 for a one hour session. I visited Yoga Tree (I think) in the Castro once, at an even higher price. The 'advantage' was that the studio was fancier, and they had a couple of really poorly trained lackeys running around making 'corrections'. Honestly, the yoga instruction I got at Mission Cliffs was better, and the instructor bothered to get to know me and my personal limitations.

I agree entirely about investing in health, though, particularly for people in sedentary careers.

I practiced at Yoga Tree Castro for a long time, and found the instruction to be excellent and worth every penny.

Have never been to Mission Cliffs, so I won't claim it's not better still. But my perspective is that any yoga class which is worth my time, my sweat, my hard work, and the trouble of going there, is worth my $15.

And, if you buy the 20-class passes, it comes out at $11 a pop.

I pay $52 per month to a local climbing gym (BRC) in Boulder and get the same thing. I personally wouldn't pay $130 for a yoga membership, but can't fault someone for doing it if that is what keeps them active. So many people in the US have a problem staying active.
