View Full Version : Why do i feel so sick after intense cardio?

Hi there, I've been doing hill running recently, and when i'm done, i usually feel as if i'm going to throw up and very dizzy. I take a multi-vitamin every day and usually maintain a well balanced diet???? Any ideas? In the past, when i would even do a hard mile or mile and a half, i would generally only be out of breath and tired, but not dizzy and sick.

Because its intense, look at the whole debate about cardio.

Some believe intensity is more important than sustained workload.

I disagree, I think some people are built for running and some arent, you dont have to run and fatigue yourself to strengthen your heart. Even if it may be the best way.

After a hard cardio session I often feel the same.

Do you eat before cardio, well at least get something in perhaps an hour before? Often if i go in very light on my stomach i feel worse after.

yeah it'd be a good idea to have a powerbar or something about a hour before. And stay hydrated. keep drinking water through your workout.

I feel that way all the time after any really intense workout untill the endorphins kick in and then I feel great. It just comes with the territory. You might want to work on your breathing though that might help the dizzy feeling. And as stpatrick says, stay hydrated. I try to get down at least .5 of a liter of water during a workout and another .5 right after.

If intense cardio makes you sick, don't do it.

You don't even really need cardio.

I run a mile 3 days a week because I've started to enjoy it, if you dont' like to run don't do it.

I've lost another 6 lbs so far since I started eating less and still just lifting hard, so I really don't think cardio is needed, cuz a mile sure as hell ain't gonna burn fat.
