Wow, this thread is a glowing testimonial for this product. I have been able to check out the Abs-Ripper-X part (the ~15 min abs program). I could not do it without taking breaks. I think Tony Horton is the man. He really describes these motions well.
I do think that it might have been better for him to say things like, "Don't you wuss out on me, you maggot, you keep knocking these out!" instead of, "if you need to take a break, go ahead", but he may fear being sued.
I am interested in the yoga-asana routine he has. 90 minutes is long, but he takes his time with the salutations, not going too fast, which I prefer. My back is not so young these days. I have not done that routine yet, but have looked at the tape (right -- no help that is!) I will hopefully do the yoga tomorrow morning.
If I could only do the yoga every morning, and the abs routine three times a week, I would be happy. That is a corruption of his program, but, hey, I'm a weird guy.
I definitely look forward to purchasing this product. A righteous personal trainer such as Tony Horton deserves no less. I am quite impressed, especially after hearing such good things about it on this thread!
