I've just started boxing as an occasional substitute for a run when I'm feeling bored or just don't feel like running, but want the excerise. I have access to a big body bag that I like to pound on for three, five or so minute sessions with a minute or two rest in between. I was wonder if there are any boxers out there that could give me some tips or ideas for a workout. I think this will be especially important the week before we all ship to OCS. I'm going to keep running of course, but I want my legs fresh when I get there, hence boxing as an aerobic excerise alternative.
