Hey there! I have done different types of yoga in the past. There are a few types, some for weight loss, some for conditioning, relaxation, etc. I also know that there are plenty of DVD's that offer different ability levels to follow. And from my experience it's absolutely wonderful. I feel energized, limber and relaxed beyond anything I've ever felt. And it's not as intense as jumping around like a fool. It's very centered and can be spiritual as well. Nice way to clear your head, stretch your muscles and center your awareness! A good 'instructor' to look for is Rodney Yee. Good luck!!!
