Warm-up exercises are an integral part of Kung Fu training. The muscles of the body are susceptible to injuries when they are not thoroughly warmed up and limber.
Before each training session, warm up with a reasonable amount of the basic exercises. Practise all the movements slow and fast, soft and hard; the effectiveness of Jeet Kune-Do depends on split-second timing and reflexive action, which can be achieved only through repetitious practice.
When performing the movements, always use your imagination. Picture your adversary attacking, and use Jeet Kune-Do techniques in response to this imagined attack.
As these techniques become more innate, new meaning will begin to emerge and better technique can be formulated.
Karate students who complain about knuckle push-ups should try doing them with two fingers instead of one hand!
