President Obama fits in 45 minutes of exercise six days a week.
The President gets his workouts in before his day starts, though he admits that there's "always a tradeoff" between getting sleep and getting exercise.
But he's firm about lifting or cardio being a part of his routine, plus his regular basketball games.
"You have to exercise," he tells Vanity Fair. "Or at some point you'll just break down."
Former Microsoft CEO Bill Gates spends an hour every morning running on the treadmill.
The billionaire and global health advocate takes care of his own health with a trot on the treadmill nestled inside his 66,000 square foot home.
Since he has an endless appetite for knowledge, he watches courses from the Teaching Company while getting his morning jog in.
To keep up with the Dallas Mavericks, billionaire Mark Cuban gets at least an hour of exercise almost every day.
Owning an athletics franchise doesn't make you fit, but Cuban knows how to do the work.
"I try to do cardio for at least an hour, six or seven days a week, knowing I'll miss a day or two now and then because of travel," he tells the Dallas Morning News. "I do elliptical and the stair gauntlet; play basketball; and take kickboxing and Latin fusion aerobic classes at Lifetime Fitness."
Virgin founder Richard Branson says that he can't go a day without exercise.
At 64, Branson reportedly still parties every night when he's at home on his island in the Caribbean.
Branson, who says he works out more for fitness than weight, takes a hybrid approach to well-being.
"I pop into the gym when I'm traveling, play tennis and kitesurf, and ran the marathon last year," he tells the Daily Mail.
Media mogul Oprah Winfrey maintains a morning and evening workout routine.
Winfrey's trainer Bob Greene recently dished on the talk show host's training regimen.
It's pretty rigorous, with at least 45 minutes of cardio and 30 minutes of strength training six days a week, complete with squats, chest presses, and inclined presses.
Starwood Hotels & Resorts' CEO Frits van Paaschen runs 10 miles a day.
Before he spends the day running the conglomerate that owns Westin, Sheraton, and W Hotels, he starts with a long run: 10 miles a day, beginning at 6 a.m.
"Van Paasschen credits running with much of his management style. Business, he says, is about conquering personal fears, setting high goals for yourself and breaking barriers, which in many ways meshes with Starwood's culture," wrote Barbara De Lollis at USA Today.
He also does triathlons — 2.4 miles of swimming, 112 miles of cycling, and a 26.2-mile run — without a problem.
The runs help him get a bearing of the many locations his work takes him.
"A run in the morning is sometimes the best way to see a place right, particularly if the rest of your day is booked," he says. "You end up in some places you wouldn't expect."
Investor and PayPal cofounder Max Levchin cycles like a maniac.
Levchin is known for his obsessive attention to detail — it helped him, Peter Thiel, and Elon Musk make a gigantic splash with PayPal.
Beyond startups, Levchin is obsessed with cycling.
Men's Health paints a picture of his routine:
Every morning at about 5 a.m. a flaming blur of Spandex we will call Levbot 2.0 careens out of its San Francisco home and into the darkness. On a typical morning, Levbot will zoom across the Golden Gate Bridge and scale the Shoreline Highway on the way to Point Reyes. After heading home, Levchin inputs data on his power output, heart rate and weight into software that he built himself. In fact, his bike collects eight different data points including cadence, power, heart rate and gradient.
Mint.com founder Aaron Patzer runs, climbs, and lifts weights.
If you're going to push through the startup grind you have to stay active.
Patzer — who sold Mint to Intuit for $170 million — provides a case study.
"You cannot work 14-hour days without getting a good workout in as a break," Patzer says.
He describes his typical day as working from 9 a.m to 7 p.m., then taking a two-hour break to work out and have dinner, and then spending a few hours more on work until midnight.
"If there was no break with physical activity," he says, "you'd be more tired and less alert."
Vogue editor-in-chief Anna Wintour plays tennis every morning.
Wintour gets up every morning at 5:45 for an hour of tennis — before she gets her famous daily blowout.
When she's at home in New York she heads to the Midtown Tennis Club, where lots of fashion folk swing rackets.
Her trainer Byron Spence says she's dogged on the court.
"She's like a retriever," he tells the New York Times. "She's so fast. She'll chase down everything. She doesn't hit with a lot of spin, but she has an amazing cross-court forehand."
The icon loves the game so much that she skipped New York Fashion Week to attend the US Open.
