T-Tapping really works. I lost about 11 total inches in the first month. It really tones you and the more you learn about the form, the harder you work. It's great.The book is easy to read. And you can figure out the exercises from the pictures. Just remember that it takes a little time to figure out. And it doesn't take near as long to do later as the first time you do it. :)I will be purchasing the DVD's, but the book is a must have as it gives you lots of tips about your form.
