I've always jogged on and off, so cardio is already taken care of.
The word "Cardio" just kills me. The most obvious reason for that is, if you think about what your bodies response to "Cardio"-like exercises, such as Jogging, Rowing, Elliptical, etc, and you compare it to your body's response after you've done a 200m dash with some connecting vaults, you'll pretty much understand that jogging doesn't quite do the trick
The reason for that is, jogging covers a completely different metabolic pathway than more explosive type exercises, such as interconnecting vaults, running, etc.
