When most fighters struggle with cardiovascular conditioning and increasing their endurance, they figure the key must be in their roadwork and amount of time they spend getting their heart rate up. Sometimes that’s the case, but the secret may also lie in another aspect of your training. There are things some fighters do, habits some fighters have that rob them of the oxygen they need. Like poor conditioning, these habits leave them huffing and puffing for air. If you’re putting in the right amount of time in the gym, hitting the road often enough and training with the intensity you should, then it may all come down to better breathing.
