I do really hate the idea of HIT but its not something i perfer. I usually throw in a shock week of strip sets, pyramids and ETC at the end of a workout. I follow that week with a full week off to totally recover.
The biggest problem i see with the HIT program is that people end up in a state of overtraining or catabolism. Most people do not have the knowledge to feed their bodies correctly to recover from failure/overload type workouts!
I am a big believer in doing what works for you though. I did not mean to discourage anyone from doing this type of routine, if its what works best for them.
