Alright well, I'll definitely look into Tabata, I wasn't super set on crossfit, I'm just looking for a really good well-rounded way of working out. I was looking at crossfit because I had heard good things and have seen things that lead me to believe that the US military special operations community are starting to gear towards it more, which is my ending goal. But by all means I'll check it out, I'm completely open-minded about this whole thing, thanks Tekk. I appreciate the input.
