Pack light, eat healthy, etc. etc.--we've all heard the conventional wisdom about what offers us the most optimal business travel experience. It's often easier said than done, but these two CEOs have got it down. They've figured out the best ways to keep fit and healthy, and they've got clever and useful tricks for packing efficiently. Follow their lead and get ready to revolutionize your travel experience.

Brian Spaly, CEO of online menswear retailer Trunk Club, travels regularly to check in at Truck Club's brick-and-mortar clubhouse locations. And as a regular traveler, he's developed a series of surprising tricks for staying healthy on the road. Here are a couple highlights:

1. Don't empty your fridge. 

While most of us try to avoid grocery shopping before we travel, Spaly says that you should keep your pantry stocked with healthy food. That way, you'll resist the temptation to eat unhealthily in the days leading up to your trip. Plus, Spaly says, you should "Make sure to keep healthy food at home so that you can take it with you." Fruit, vegetables, and nuts that you bring along will be cheaper and far healthier than anything you can pick up in the airport.

2. Don't take taxis. 

It's tempting to hail a cab, uber car, or a rideshare when you're in a new city and want to go from place to place. But Spaly recommends walking instead. Pick a hotel in a central location so that you can walk to restaurants and meetings. It'll help you make time to exercise and stay fit. The difference between walking and taking a cab, he says, is only about ten minutes, and, as Spaly points out, "it's the difference between feeling good and not feeling good when you sit down at dinner."

Bruce Turkel, road warrior and CEO of Turkel Brands, is an expert at traveling light when he's jetting around the world on business. But he does it without compromising on his needs. Here's how.

3. Pack a collapsible jacket. 

Turkel never leaves home without a collapsible jacket. This might seem like an impractical item, but you never know when you'll need it. As Turkel points out, "even if you're going somewhere warm the airport is going to be freezing or the plane is going to be freezing." He's got a jacket that collapses down so that it's the size of a couple of pairs of socks, and it's always in his luggage.

4. Pack efficient clothes.  

Turkel's t-shirts aren't cotton--they're merino wool. "I thought it would be itchy and uncomfortable and it's not at all," he says, "You can wash it in the sink and it dries quickly."  And while you might expect a busy CEO to take advantage of hotel laundry services, Turkel's got other plans. He travels with ExOfficio travel underwear, which don't absorb moisture and dry out quickly, and washes them in the sink. "I get it. It's funny," he admits, "But you know what? I don't care because I'm obsessed and it works."
