I take a class at the Newark YMCA called Cardio Strength plus that is pretty intense.
I was watching an infomercial the other day about the tapout XT workout.
I told the instructor about it and he looked into the work out.
So he decided last night to incorporate about 20 minutes into his one hour class.
Holy crap!!!! that was nuts!!!
this guy is a MMA trainer.
has anyone tried it. It was the toughest workout I have ever done.

I enjoy this type of workout but my go to one is Bas Rutten's MMA Workout. http://www.amazon.com/Bas-Rutten-MMA-System-Workout/dp/B0013Z4R78/ref=sr_1_1?ie=UTF8&qid=1340303536&sr=8-1&keywords=bas+rutten

This was actually one of the things he used when he was training and other fighters use it or something similar as well (BJ Penn has said he liked it, Duane Ludwig uses it, etc).

I'll have to check out this one you posted and maybe incorporate some of the stuff into my workouts. Thanks for the link.
