4 hours sleep and great workout?

[tweak05]

so yesterday I woke up at 6 in the morning for no reason, I was only asleep for 4 hours so it made me pretty angry. So I get up pissed, end up going to the gym around 9, do HIIT for 20 minutes no problem and do the most intense delt/trap workout I think I've ever done. I just had so much energy, I did an extra 7 sets just for delts and was drop setting every set with db shrugs. I just dont understand, but I think I got away with it because I'm so young. 18 can have its advantages. Anybody else ever done something like this?

Anybody else ever done something like this?

Sure.  Every now and then I get less sleep than usual, and wake up feeling better and more energized than if I sleep longer.  In my experience though, when it happens "every now and then", I'm fine.  But if it becomes constant, (ie getting four or five hours EVERY night), I end up feeling like crap after a while.  I also find that sleeping much more than eight hours a night leaves me feeling groggy and run down the next day.

Actually, after consistently getting 6 hours of sleep a night for several nights in a row, i'm finding it really difficult to sleep all night.  Further, i'm feeling tired all the time.  Maybe i'm overtraining, but i only train 4 days a week!

yep, one of my best workouts. was the time i didnt never sleep at all.  the only part the sucks is when you crush. nervous energy, you gotta love it.

My personal max on the bench press (595lbs) was achieved after working a straight-through 60 hour shift with no sleep.  Go figure.

That happened to me too. One time I stayed up all night studying to two, back to back, midterms the next day. Right after the midterms I did a back workout. Usually I'll start off with five sets of bodyweight wide grip chins but on that day it seemed that it was to light and I strapped on a 25 and did a set of six good reps. I had some good strength that day

Oh yeah, I should also mention that 2 days later, I fell asleep WHILE running on a treadmill and got shot out of the machine like a tube of toothpaste!

It does happen.  IMO what occurs is you hit a few deep cycles during the shorter sleep leaving the body just as rested had you slept 8 hours (same number of deep cycles).  The body probably somehow regenerated the same ATP and therefore your workout did not suffer whatsoever.

[Bear03]

sometimes it gives you a natural high

but

it's dangerous to run many days without sleep

a damn good way to overtrain.  that's what happened to me.

now i'm on the verge of being sick, have a damaged rotator cuff, have stopped growing, and am generally tired.  not getting sleep = terrible, terrible idea.
