Sounds like your blood sugars maybe Embarassedcould be off.

 Its blood flow because you probably didn't eat prior and worked too hard. Make a whey shake with some fruit, you'll be as good as new ;]

Oh my gosh, I feel the same way after lifting weights. Right after I finish, I get in bed (I lift sort of late ;;) and I'm just sitting there, and I can feel my arms shaking for a few minutes...
It's low blood sugar. I have that issue. A glass of OJ or a couple of apples fixes it for me. =)
OJ fixes it for two reasons - one is low blood sugar. The other is because it has potassium in it. Muscles spasms are caused by an imbalance of electrolytes. When you sweat, you lose salts, like sodium and potassium. You need to replace the salts you lost during your workout.
I have never heard of workouts causing hypoglycemia. I even Googled those keywords and found nothing. I have a condition that causes hypoglycemia and it makes you feel weak and dizzy, not jittery. But low blood sugar can result in an adrenaline rush from the body trying to rescue itself from a hypoglycemic state. I think because of that people identify hypoglycemia with jitteriness when jitteriness is not the direct result of hypoglycemia, its an after effect (from the adrenaline rush). Intense workouts will also produce adrenaline rushes! I would say its just adrenaline! But I think this is one of the reasons that a "cool down" is important after a workout, and eating a snack 30-60 minutes before a workout is also always recommended (to "fuel up", not to 'make sure your blood sugar doesn't drop to low'). A normal healthy person should be able to exercise without it resulting in hypoglycemia.  But hey, I could be wrong, I'm no Dr.!
