Fighters need to stop slow aerobic training!
Now before you start losing your mind, let me explain. For a long time fighters have known that, in order to get in shape, they must do their roadwork. Getting up at five in the morning, lacing up their running shoes, and hitting the pavement. Most of the time, fighters will run as far as 10-20 miles, before even fully starting up a day of training.
What seems to be the problem with this is that most of the sports requirements are anaerobic in nature. Yet studies have shown that aerobic training actually makes athletes slower.
