The information itself is not new. It’s been known for about 60 years as to the effectiveness of HIT training.
What 90X does though is package the information in a usable way for most consumers, because most people know very little about training effectively for good results.
It’s not a lot of money to be the program and I think that, even if you only learned one thing you didn’t know before, it’s worth the money. But that is my opinion.
Thanks for the response. But is 90x HIT? It doesn’t really sound like HIT to me.
Maybe I will check it out once I am finished with this current routine (a couple more months).
