I've taken a few classes at the local yoga studio with my gf. I like it and see some increased flexibility. I want to try and do it once a week (about all my budget will allow at this point) because I'm going more aggressive with my bike fit. We get their early to get a spot. Also depends on the instructor - the one I like is more focused on the physical side and less on the spiritual (although she does include a little of that). But I've been pleased overall.
