Welcome to SaddoBoxing, firstly jogging (like Youngblood said) is just one exercise of so much more. There are many different aspects of conditioning and jogging targest one of three systems: aerobic system. Interval training, minute drills, etc are also exceptional for conditioning. I highly recommend RossTraining - Bridging The Gap Between Ordinary and Extraordinary and Your Top Source For Free Boxing Training Advice. Both websites are much more focused on the strength/conditioning aspect of boxing than this website and less so on the skill/technique aspects.
