Yep. Jumping/moving sort of pushes things through. Totally normal.

Yup, all that movement increases your movements in the intestines... which = more bowel movements!

It happens to me too.

Yep, that's one of the benefits of exercising--it keeps things moving as they should. And that includes toxins out of your body, so that's a great thing!

Yes. There is a question in Fitness magazine this month about it.

Well, that's good!! Nothing to worry about. There was a time when I had to interrupt my running on the treadmill and rush to the bathroom for the same reason and then my body adjusted and I could wait until I was finished running.

lol this is the main reason why I'm so glad I have my treadmill at home

I think this is pretty normal. It happens to my husband (who came home after a run with only one sock, because he had to use the other sock in the bushes...) and apparently this happens to a whole bunch of people, especially when they start to become active.

Quite possibly the most embarrassing story invoved Paula Rutledge, the British Marathoner, who just couldn't hold it in anymore and had to do a very public BM along the side of the route at mile 22 of the London Marathon in 2005. In front of thousands of spectators, and a million viewers LIVE on TV...
So take heart! Just keep at it. You ROCK!
