I second Mastercracker. I've been doing yoga off and on for seven years, and the cracking definitely increases when I do it more often (more frequent, more joints). Yoga increases cracking, at least for me. But it feels freakin good!

The benefits of yoga are many… I highly recommend it to everyone here. But everyone has their own priorities and goals, and I'd say if you are trying to NOT crack, then don't get your hopes up with thinking yoga is the cure...quite the opposite in my experience.

If you want to be more aware of and in tune with your body, and if you like the idea of learning to accept and embrace it as it is, then by all means go to yoga.

Namaste!
