Ok i was wondering if after traing or excercising is it normal to shake???after i finish all my mussles just shake and twitch im just wondering if thats nomal or not

A suggestion on this type of questions. Add waaay more details.
Even if you go to a doctor (and from the little you described we don't know if it's a medical problem or not), you are likely to waste your money and get a bad diagnosis if you are vague and force people to guess. You should instead come prepared with a lot of details.
Write down somewhere and keep track of things like:
-Did you always have it? Has it been getting worse? How long does it last? How intense is it?
-When exactly does it happen and when doesn't it happen? (for example is it only when you do very intense exercise? Or does it depend on the length of time? Is it only in the muscles you worked on or any random muscle?)
-Is it a type of shaking that only happens when you try to move? For example when muscles are very fatigued it's hard to control and balance opposite muscles for fine control, say keeping your hands from shaking a bit if you try to keep them open and still in mid-air. But if you lay down and keep your hands completely relaxed on a pillow they wouldn't shake on their own at all.
-Is the shaking a twitching of your muscles or is it related to other things like your blood vessels pumping at a similar pace as your heart like Charles suggested?
Basically you should have all those details listed before asking so people don't have to guess the answers to all of these before they try to help you and give you advice.
And they will help you too, in avoiding wrong assumptions (for example if the tremor only happens when you exercise it's unlikely to be due to something like excess caffeine since that would affect you even when resting with other syptoms like increased heartbeat etc).
