Last night at the gym, I apparently pushed myself a little too hard, and I threw up all over the shower. I'd rather not do that again, so:
- What causes this?

There has also been a study that showed that exercising shortly after eating is likely to cause this. Which is supported by this article about "Nausea during a strength training workout" that suggests three common factors that contribute to workout nausea:
They also provide several tips to prevent it:

A couple ways to combat this feeling:
