Jeet Kune Do Zones and Speed Training

Although you have the right attitude,
It is not enough to avoid a strife.
Although you have a heart of fortitude,
It is no assurance of saving your life.
You May have spent years in training
In the art of fighting you loved so much.
But if you are winded in a sparring,
It proves that your condition is such
You need plenty of workout on the road,
running two,three or more miles a day
Until your body take more load.
Then comes a day you see the light,
You look up the sky and then relay:
"Skill in Performance is all right
But it is not enough to prove your might"
- Bruce Lee ( 1940-1973)
