I have read the book and have been doing the workouts approx. once a week for about a month. It is pretty tough but really only takes 30 minutes! After doing the workout, the next day I am a bit sore.

I have seen results in improved strength and some of my muscles are a bit larger as well. I am surprised because I didn't think it was possible to get results with so little time spent.

This is a great workout if you are super busy or even lazy - because you do it and then it is over for several days.

Pretty cool!
