I am wrapping up week two. Week one was hell in summertime, but week two is a little bit easier... still a killer workout, but my body is adjusting. I was shocked at how much better my body responded to Yoga the second time.
The thing I really like about this workout is that it is balanced... strength, balance, stamina, and flexibility. I have worked out a lot in the past, but never with this kind of focus on flexibility and balance. It makes a big difference.
It is expensive, but since a lot of people probably bought it for a New Years resolution & have already quit, you can probably find it cheap on Craigslist. I bought it for $50 & it included all the manuals, posters, DVD's, etc. From the website is costs over $100 plus shipping.
You do need to have some dumbells, a mat, and a way to do pullups. The workout sheets are available for free from the company website.
Good luck!
