In an expansion on the list, ZH reports this:
They exercise before it falls off the to-do list.
The top morning activity of the rich and powerful seems to be exercise, be it lifting weights at home or going to the gym.
For example, Vanderkam notes that Xerox CEO Ursula Burns schedules an hour-long personal training session at 6 a.m. twice a week. Plus, “Shark Tank” investor Kevin O’Leary gets up at 5:45 every morning and jumps on the elliptical or exercise bike, and entrepreneur Gary Vaynerchuk starts every day with an hour-long workout with his trainer. “These are incredibly busy people,” says Vanderkam. “If they make time to exercise, it must be important.”
Beyond the fact that exercising in the morning means they can’t later run out of time, Vanderkam says a pre-breakfast workout helps reduce stress later in the day, counteracts the effects of high-fat diet, and improves sleep.
I can verify the O'Leary workout, He was in San Francisco about a week ago, apparently staying at the hotel affiliated with my gym. He showed up at the gym, although, I think it was closer to 5:30 than 5:45.
A newspaper in hand, he eyed the gym equipment and stepped on a jogging machine.
