<i>An early start is followed by furious exercise. David Cush, the CEO of Virgin America, is on his exercise bike shortly after getting up at 4.15am. Tim Cook of Apple is in the gym at 5am. However strenuous the workout, it is often combined with other tasks. Mr Cush reads, makes phone calls and listens to a sports-radio station while cycling. Mr Iger once told the New York Times that, while exercising, “I look at e-mail. I surf the web. I watch a little TV, all at the same time.” And all while listening to music.</i><p>These guys probably aren&#x27;t really working all that hard. If you have time to read emails and surf the web then you should exercise harder.<p>A lot of adventure sports mostly require money eg sky-diving - cost of fuel, mountaineering - paying for the expedition. I know people who mostly spend their money on adventures. Anyone can do this if that&#x27;s your thing. Otherwise get into some cheaper adventures like rock climbing or canyoning.<p>The triathlons and mountain-biking might be impressive if we knew their times. Lots of people have jobs and families and commitments and regularly compete in and train for endurance sports or any sport for that matter. Who do you think enters these competitions?
