Jogging isnt going to get you in shape. RUNNING and most importantly SHORT SPRINTS will get you into shape. Boxing is a sport of short intense bursts of action and then some aerobic moving around.

I suggest first and foremost you spar harder, keep good technique always, but push your pace while still being in control.

Second, do workouts that combine different aspects of fitness. For example, do a 3minute round of 1minute of 20yards sprints back and forth, 1minute of push presses, 1min of cleans(light weight, this is for conditioning). then take your one minute rest and repeat it for however many rounds you need to go.

Now that is an example, but you can vary what you do each rounds. I usually include more exercises. Good ones to rotate in are, Sprints, cleans, push press, pushups, situps, pummeling, pullups, burpees, firemans carry, jumping on a 12' box or step, jump rope, ect ect. The key is, your not going to be able to do everything for 1minute straight so be flexible, if say you burn out on the push presses, then switch to pushups if you can, or maybe go to a different muscle group.

Another thing to note is for every 3minute rounds you want to distribute somewhat evenly the muscle groups worked,

So for instance, sprints, push-press, and situps, work different muscle groups. Generally for the lower body you can do sprints and cleans or some other leg movement, but for upperbody its more important to split up the pushing and pulling and not overdo it.

I recommend pacing yourself at first because this is harder than you think doing 4rounds of 3 mins or whatever you choose to do. Last rounds go all out and push yourself, as you do this more increase your pace. This is hell, itll make fighting easy.
