My friend was training for college basketball, so we were working out together a lot last summer, and went to the sand dunes. Normally people just walk up. But we sprinted full speed halfway and then back down. I made it 4 times, and then I was totally immobilized, and threw up after.
Today, I just played basketball for nearly 8 hours, when I got home I couldn't move. I had to get out of the shower because I couldn't support my own weight, and I've been on the couch, and just got up to throw up.
is it a good thing to do exercise to the point where you have to throw up? sometimes when I'm doing something I just lose track of the world and get consumed by the activity, and I guess this is the result :p .
