Training for strength and flexibility is a must. You must use it to support your techniques. Techniques alone are no good if you don't support them with strength and flexibility.
Bruce LeeWhile it may come as a profound surprise to those of us who are in the throes of an emotional or life crisis, the fact remains that the answer to virtually all of our problems resides within us already. It exist in the form of a vast reservoir of free-flowing energy that, when channeled to our muscles, can give us great strength and, when channeled to our brain, can give us great insight and understanding.
Bruce LeeForget about winning and losing; forget about pride and pain. Let your opponent graze your skin and you smash into his flesh; let him smash into your flesh and you fracture his bones; let him fracture your bones and you take his life! Do not be concerned with escaping safely- lay your life before him!!
Bruce Lee
