Hi...
I'm new around here, but wanted to let you know that I have done T-Tapp and intend to continue with the program. It is an excellent program that delivers what it promises. If you do the tapes as directed you will see dramatic inch loss. It is a different exercise program than any other I have used (and I have tried LOTS). I used the program before I started doing weight lifting again, so I don't know if the inch loss would be as dramatic for someone already involved in muscle building through weights, but I can say I don't think you will be disappointed.
If you want to read a bunch more about T-Tapp you can read posts on the Weight watchers web site - there's a message board there called Fitness Getting Started and another called Fitness Challenge where people regularly discuss the tapes. Also, they are available from ebay sometimes and at other sites for less money.
Good luck!
