Jeepers, I didn't realize how out of shape I was. Time was I could do a hundred situps, pushups, and jumping jacks all in a row. Now, three college years and a video gaming hobby later, this is the first time I've ever felt sick from working out. I managed 50 situps OK, but then couldn't do more than 30 jumping jacks from the nausea and only 20 pushups.

Some years ago I was recommended 30 minutes of exercise by my doctor. Obviously I need it.

<edit>
OK, after a rest I did manage to do 50 of each, but I think I may have hurt myself. I don't really know how to do a proper situp.
