Looking for sites with good MMA weight lifting/cardio workouts

I know there’s quite a few practicing martial artists in here. I have some Tae Kwon Do background with a good chunk of good ol’ high school wrestling and some boxing. Although I’m not gonna end up doing any MMA fights, I’m still very interested in how these guys workout and train. I’ve been looking at a bunch of sites but would like you guys personal recommendations. Thanks.
