Personally i've never really been able to work out the benefit Boxer's gain from 4 mile jogs. It's purely an aerobic workout whereas Boxing is more of an anaerobic sport. I would have thought interval running would have the most benefit.

Even for weight loss (to make weight for a fight) it would still make more sense (to me) to do intervals seen as though short intense forms of cardio are the best for fat loss while wanting to maintain muscle tissue.

Can anybody enlighten me? There must be benefits that i'm missing.
