Your body is trying to tell you something. Pay attention to how much time elapses in between high intensity work outs and observe what and when you are eating prior to doing something more intense like HITT. Less than a week of not working out much induces feelings of nausea for me when I finally do return to the treadmill, as does eating too soon (or eating something heavier) before running.

Try determining your maximum heart rate and not exceeding it. In an excercise physiology course I took the professor said that the urge to vomit could come on if you exceeded your maximum recommended cardio heart rate for a short length of time. You don't even have to be doing cardio for this to happen. Just really have to get your heart racing. In fact, I find it happens to me more lifting weights then on cardio machines. The machines have heart rate monitors at the local gym so I don't get ahead of myself because an alarm sounds if you get to high. This happened to me ALL the time when I exceeded my maximum heart rate lifting weights. Everytime I'd get the urge to vomit while lifting I'd take my pulse and it would be above what it should be. Try slowing or taking 30 seconds to rest if your heart really seems to be pounding. You can add time between sets too until it's not a problem. Once the urge to vomit comes on it's hard to get rid of and this advice won't help. The key is not to get there. Which makes it hard. Stopping to feel for a pulse is a pain. I get around it by exercising my cardio on machines that monitor heart rate for me. They also sell some monitors you can wear. I don't remember exactly why she said it happens but putting your head between your legs and having electrolytes should rid you of the feeling but can return easily if you go back to exercising once the feeling hits. Some of it is dehydration as others have said. But there are also other reasons dealing with the body that you are getting the feeling. I think part of the reason she's given was a lack of oxygen to the brain triggering nausea.
There could be various factors for that to happen, but I have seen this happen due to heat and pushing yourself too hard. Definitely make sure you are eating enough for your activity level, stay hydrated and be mindful of how hard you are working (and be mindful of the temperature and humidity, especially if you are exercising outdoors). Pushing yourself is one thing, but if you push yourself too hard, it can cause vomiting, among other things.

Sounds like low blood sugar. I'd try making sure you had something to eat 2 hours before you attempt that workout again.

A while back I was pretty motivated and lifted weights (squats, deadlifts, etc) with more sets then usual, probably twice as many.... When I finished, I was not feeling particularly well, but I thought probably I was tired. But a few hours later I felt worse, my stomach was upset, I felt like throwing up. But I hate throwing up, so I fought it. Of course I got scared, and got my blood pressure checked etc, but I was finally told there was nothing worrisome about my health. I actually posted a message on that incident in this forum.
My take from all this is that when you push your body hard enough, it can respond rather nastily. Now I think I pushed pretty hard that day, probably I should not have pushed that hard. I think your case too has probably resulted from pushing too hard.

Thanks for the reply.
I do believe I've been eating enough for my size. Usually 1200- 1500 daily. Occasionally I'll go over or under, but I try to stay in that range.
I just hope I don't get so sick again :/

I have a friend who used to do that, and it turns out it was caused by not eating enough to support her workouts. She was skipping breakfast thanks to that whole "burning more fat on an empty stomach" myth, and her blood sugar was crashing big time. She was also undereating (at the time, 1200 calories, and she was a big girl like me, and working out seriously hard - boot camp hard.)

Hehe, good to know! Wasn't stating a "fact" by any means. Basically saying, "I don't believe I worked hard enough in comparison to my normal workouts to justify vomiting".
I feel better now, so I don't think I'm virus sick or anything.

you're probably sick.
just want to clarify though: I have thrown up WAY more racing 5Ks (pretty much every time) than I have running marathons (never).

Yesterday was a rest day. Today i felt pretty good, but a bit sleepy (i took a lil nap mid afternoon). A while after that, I had more energy and I decided to not be a total bum and get my workout in.
Instead, I threw up, got super shaky, and almost passed out! I feel crummy even right now. Bleh!!
So whats going on? Does anyone have experience with exercise induced vomiting? How bad is it for your body? Did I commit an exercise sin or is this something that sometimes happens? I know marathon runners throw up, but I think that's fair, all things considered :P. Since I didn't just run a marathon, and have been physically active and trying to eat right, I can't figure it out.
