I've trained MMA in the past and have had (unsuccessful) attempts at three fights (2 fights cancelled and 1 I got sick two days out) before walking away for almost one year now. Make no mistake that I've done the training before and been in wars in the gym and that I'm not just a home warrior (or whatever the terminology is). I want to try again at a fight but my gas tank stinks for obvious reasons. I ran a two mile course and was not impressed. Please know, also, that I understand the best cardio will come from training partners in the gym who want to best you to feed their egos; I just need to get back to formidable shape so I'm not just a punching bag for them. Can anyone direct me to a regimen be it found in a book, DVD, Youtube channel, etc. that deals with getting back into fighting shape? Bonus points for MMA striker oriented workouts?
