What does "metabolic training" mean? Where I work out they call it "functional fitness".

The thing is, cross fit didn't really come with anything new, they just packaged it. There is only so much "new" stuff that has been invented for fitness. Most of the new thinking on fitness pulls from the same new thinking: multi discipline, higher intensity. Much of it , including the training I do (so this is not meant to be disparaging) is glorified circuit training: multiple kinds of movement done at a higher intensity. By multiple discipline, I mean pulling from many different schools of exercise such as weights, cardio, plyometrics, yoga, balance work, Pilates and so on combined together.

I think that the big thing is working with people who really understand what they are teaching,are knowledgable, and understand the differences in bodies, fitness levels, and abilities to help people get the most out of it.
