Is there some where I can find a meaningful description of each individual exercise that comes with the kinect version of Active 2? I've never taken fitness classes or worked out at a gym so I am unfamiliar with much of the terminology and the names of some of the exercises don't mean anything to me. If there is not a list with description, is there a way to tryout each individual exercise/or view the tutorials one at a time without it having them as part of a workout?

One that I am currently wondering about is "Fitness Trail - Follow the leader." Is the is fast run, leisurely jog or something else entirely?

Follow the leader is an exercise where you go with the trainer doing various things, running, high knees, kick ups. etc. If you go into the custom workout section you can build yourself a little workout with the things you want to see.
