I started doing Iyengar yoga a few months ago, I have scoliosis and I'm a tattooer so my back is fucking SHOT. After a few weeks, I felt like a new man. Pretty remarkable how much better I felt almost immediately. I've ben going a few times a week pretty consistently now, I find that not only am I physically feeling better but I'm also a lot more mentally focused. I highly recommend it. The real shit though, like Mysore or Iyengar style, not that jazzercize bullshit they do some places.
Any of you other dudes into it?
