Sprint training is by far the best sort if i understand your question.
Distance running is not really apropriate for MA in my opinion unless you are trying to loose weight.
Ok best way to do it is to find a steep hill (about 200 meters) and run up it either against a watch or against a training parttner as it is easy to not push your self.
Repeat this about 3 times at the start of your training then get up to around 9-10 times when you are good.
I find this really pushes my stamina up for san shou really fast.
It is worth remembering that when you stop training stamina drops off much faster than you would think.
LOL.. really, what else did you hear?.. did you hear that he was voted Man of the Year by Kung-Fu Magizine?
