I was excited about the workout. I had been warned that it's not unusual to vomit after.
A group of 16 "students" of trainer Chris LaLanne -- the grand-nephew of fitness legend Jack LaLanne --- took off right at noon, jogging from Second and Howard Streets toward the Embarcadero. It was hot, about 83 degrees. The sidewalk was filled with workers on their lunch break. We were treated as a spectacle, like a sweaty flash mob.
