I love the concept of this kind of training. If I wanted to go to a gym more often, I would definitly choose this kind of training. It is super efficient! To me, this kind of training makes the most sense. However, I would still want to go on my long, slow hikes on the weekends and, for proponents of HIIT, they would say that would easily push my body into overtraining. Regardless, if I could really design my own routine, the links you provided and the information therein would be the mainstay of my program.
Working out to get great results is really about high intensity in a short amount of time, so as to optimize muscle growth and minimize overtraining.
I think if you are thinking about this method, I would for sure go for it. I will have to go back and look at all your links just to make sure I have seen them all!!
Sorry I can't really report on any results. This method is limited for me in its "true" form because I don't have a spotter. I would love to find someone as serious about working out as me though to test this program. Great fun!!
