We've all had those days when you know you should work out, but you have absolutely no motivation to do so.

It may encourage you to hear that exercise really is super good for you. There's a mountain of research backing up its many benefits.

The US Centers for Disease Control and Prevention recommend at least 2.5 hours of moderate cardio activity or 1.25 hours of vigorous cardio activity every week, plus two days of strength training.

You can work up to that goal by starting small, though.

To motivate you to get moving, here are 21 research-based benefits of exercise:

No one likes to pick up the phone and call for delivery or take-out anymore. Instead, more and more food delivery is shifting to online, where you can order from just a few taps in an app.

The question is: Which app do you choose?

Business Insider put seven apps to the test to see which could bring us the freshest, fastest, and cheapest lunch.

There's a lot of options out there, but after trying seven head-to-head, we've ranked the ones we're most likely to use again.

In the US, analysts estimate that only 10% of restaurants take online orders. That means there's 90% of the market left to conquer, which has created a gold rush of companies trying to cash in. Right now, GrubHub is the market leader in terms of ordering share. But is it really the best service?

San Francisco is a test bed for the biggest market leaders in food delivery, so we decided to find out. We ordered from seven different services — GrubHub, Eat24, Caviar, DoorDash, Postmates, UberEats, and Amazon Prime Now — in the ultimate delivery showdown.

Who are all these contenders? You've probably heard of GrubHub, which operates in more than 900 cities and owns Seamless as well as a few other smaller delivery companies.

Depending on the restaurant and city, a restaurant will either send its own delivery staff after receiving a GrubHub order or the company will supply its own pick-up people.

Shaun Hergatt is opening an exclusive new restaurant in the middle of Manhattan.

And before you think about booking reservations, ask yourself if you know anyone who lives at 432 Park Avenue. 

The Michelin-starred chef's restaurant is private, meaning only residents or guests of residents at the Midtown apartment building can dine there, according to The New York Times. 

The restaurant will open this fall and is located on the 12th floor of the 96-story residence. When the building's construction is complete, 432 Park Avenue will be the tallest residential building in the Western Hemisphere.

Chef Hergatt previously displayed his culinary skills at Juni, until the restaurant closed in May.

The up-and-coming restaurant has yet to be named, and will span the entire floor, complete with a terrace and lounge area. Bentel & Bentel is the design team behind the restuarant and Rafael Viñoly Architectsis designing the building.

NOW WATCH: Everyday phrases that even smart people say incorrectly

Jacob Laukaitis is a self-proclaimed digital nomad who has been traveling the world while running his online business, ChameleonJohn, for the last two and a half years.

Laukaitis, originally from Lithuania, has traveled to nearly 50 countries and is constantly in search of global destinations that are truly unique. After watching multiple documentaries and reading up on North Korea, he decided to pay the hermit kingdom a visit in April.

Laukaitis shared some photos from his one-week trip, from the bizarre tourist attractions he saw to the fascinating aspects of daily life that he witnessed:

Before his arrival, Laukaitis' phone — including any photos and apps that were on it — were inspected by officials. Outside the airport, he was met by his guides and told that he would not be allowed to take photos of police, military, or government officials during his trip.

One place that they were able to visit was Puhung Station in Pyongyang, one of the world's deepest metro stations. Laukaitis and his tour group were allowed to ride the subway for four stops before they were told to get off.

The station was covered with daily newspapers that mostly focused on Kim Jong-un and his activities, Laukaitis said.

Harry's, the online shave club that has converted more than 2 million customers by offering an alternative to expensive drugstore-bought cartridge shaving, has upgraded its key product.

The company's signature shaving cartridges, made by its factory in Germany, have been given a complete overhaul. Among the changes are differently spaced blades for more even cutting, a better flex hinge, and a rear blade for precise edge trimming.

Harry's Co-CEO Jeff Raider told Business Insider that the changes have been in the works for nearly two years, with millions of dollars invested in the German factory to purchase new machinery. 

"We believe that companies should always strive to make their products better, and we try to do that at Harry's everyday," Raider said.

Also given a makeover are Harry's razor handles, the metallic Winston and the formerly plastic, now rubberized, Truman. The Winston was given rubber grips as well, to match its redesigned, more ergonomic shape. Raider stressed that all of the changes were made in response to customer feedback.

Prices remain unchanged for the new designs of both the cartridges (4 for $8, 8 for $12, or 16 for $28)  and the handles ($20 for the Winston and $9 for the Truman). Though the company started as a subscription model, it now lets customers order all of its products on a one-off basis.

The company raised $75.6 million in a series C funding in 2015, which powered this new generation of products and pegged the company's valuation at $750 million. Wellington Partners led the round and were joined by Tiger Global Management.

The updated products will be shipped to customers starting Tuesday.

The World Economic Forum recently announced its 2016 class of Young Global Leaders — people under the age of 40 who are changing the world — and 24 of the 121 are American.

This year's Young Global Leaders class includes leaders from an array of backgrounds. Some are famous entertainers, like actor and investor Ashton Kutcher and writer John Green, and others are inventors, CEOs, philanthropists, and scientists working on revolutionary ideas — such as Nina Tandon, who grows human bones with her biotech company, EpiBone. 

Once chosen by the WEF, these leaders are a part of the program for five years — they attend meetings, participate in initiatives and research, and work with the rest of the WEF's community.

Here are the 24 American leaders making a worldwide impact.

Andy Moon, SunFarmer

Andy Moon started his work in the solar energy industry in 2009 as a project developer for SunEdison. In 2013, he and a coworker started SunFarmer — a nonprofit that brings solar power to developing countries — with the help of a $2 million grant from a SunEdison foundation.

SunFarmer has completed more than 100 solar energy projects so far in Nepal, its pilot country, powering schools and health clinics as well as providing relief to victims following a pair of earthquakes last spring.

By 2020, SunFarmer’s goal is to power 4,000 hospitals, schools and water projects around the world.

Aria Finger, DoSomething.Org

After graduating from college in 2005, Aria Finger joined the nonprofit DoSomething.org to try to change the way young people give back to their communities. The organization has since grown from five employees to 55, and in the past decade it has helped 4.7 million young people started campaigns in their hometowns.

Six months ago, Finger was promoted to CEO. Her most recent campaign, Keep Guns Off Campus, encourages students to pressure their college presidents to take a stand against having guns on campus.

Ashton Kutcher, THORN: Digital Defenders of Children

The actor, producer, and tech investor started the DNA Foundation in 2011 with then-wife Demi Moore with the goal of ending child sex slavery. The company rebranded a year later to “Thorn: Digital Defenders of Children” with a more specific focus: technology’s role in the sexual exploitation of children.

With the help of partners such as Facebook, Tumblr, and Microsoft, Thorn has been battling Internet-enabled sexual abuse and providing support to victims. This past November, Kutcher announced that the organization would open an innovation lab that will allow data analysts and scientists to think up new technologies to deter online predatory behavior toward children.

It's been nine years since Matt Damon last played former CIA assassin Jason Bourne. The role proved Damon could be not just an action star, but also the face of a hit worldwide franchise. Damon now returns to the character in the much-anticipated "Jason Bourne" (in theaters July 29), and he's arguably in the best shape of his life.

A big part of that is thanks to trainer Jason Walsh, who has been working with Damon since the actor played a chiseled ex-criminal in the 2013 sci-fi film "Elysium."

Damon has continued to work with Walsh because of his training methods, which are dedicated more to creating an athletic physique than getting super-buff. That suited Damon, 45, as he was dealing with ailments when they first met.

"He had issues with this lower back and shoulder," Walsh recently told Business Insider of getting to know Damon. "He had heard that I'd corrected injuries with people who had been living with injuries and pain for a long time so in a couple of weeks I helped him out with his shoulder injury and soon after we got his back cleared up and he was 100-percent feeling great so we continued from there."

Walsh didn't hear from Damon for a year after "Elysium" wrapped, but then he got a call from the actor, who said that he booked three movies in a row and needed Walsh's talents.

Those movies were "The Martian," "The Great Wall" (opening in early 2017), and "Jason Bourne."

In September of 2014, they got back to work to get Damon in shape for the films.

"My biggest thing with Matt is making sure his foundation is solid, and that means he has mobility, flexibility, and overall strength," Walsh said.

"Bourne" was the final film of the three to be made, so by then Damon was in great shape. But director Paul Greengrass told Walsh that, this time around, the look Damon needed to play Bourne was of someone both mentally and physically distraught.

This led to a simple plan for Walsh's training of Damon for "Jason Bourne."

"I just kicked the s--- out of him without breaking him," Walsh said.

Leading up to filming and during production, Walsh had Damon work out on a VersaClimber, which is a piece of cardio equipment that works out the entire body as you pull up and down with your arms and legs in a standing position (almost like climbing a mountain, but doing it much faster).

In this Instagram video, Damon (on the left) can be seen working out on the machine alongside Walsh during filming of “Jason Bourne.”

“If you could see his face after that one, it was fantastic," Walsh said of the video. "He literally sat down next to the wall and looked like he was about to chuck."

Workouts with the VersaClimber that Walsh came up with included seeing how fast you can get to 200 feet or going as fast as you can for one minute. (Walsh, who's also trained Bradley Cooper and Justin Timberlake, among other stars, gives VersaClimber classes known as Rise Nation. He has two locations in Los Angeles and one coming soon to New York City.)

But that wasn't all. Walsh also incorporated daily workouts like:

- 100 sit-ups
- 300 push-ups
- Squats (50 reps)
- Squat jumps (50 reps)
- Pull-ups with 35 pounds strapped to waist
- Single-leg squats with 125-pound dumbbells in each hand
- Sled push and pulling

Along with Damon's chef giving him around 2,000 calories a day during shooting, Walsh also cut back Damon's water intake. Nearing dehydration showcased his body's glamour muscles.

"You start off drinking quite a bit of water the week leading up to shooting," Walsh said. "And then you start cutting back around two days before a specific shooting day, and then on the day [of shooting] you don't have much water in your system."

This method was used while shooting the boxing scene that's been showcased in the "Jason Bourne" trailers, in which Damon knocks out his opponent with one quick punch.

Walsh said that when a photo of Damon shirtless on the "Bourne" set hit the internet and instantly became a trending topic, he couldn't have been prouder.

"He worked his a-- off," Walsh said. "A lot of people don't know what it's like to work that hard and work that long, we had been working out for a year and a half straight! I'm really proud of him."

But every person has their breaking point, and Damon's came when "Bourne" wrapped.

"The day of wrapping there was a large pizza waiting for him," Walsh said.

NOW WATCH: Researchers found out how many miles a week you need to run to improve your health — and it’s surprisingly low

The Four Seasons Restaurant has closed after over 50 years of welcoming New York's elite into its ethereal dining room.

So now, after weeks of parties in which people jumped into the restaurant's famed pool, dined on food prepared by celebrity chefs, and generally mourned the passing of a legend, one thing remains: You still have to go somewhere to power lunch.

While we cannot bring back The Four Seasons, we can make a few suggestions as to where you might sit in a space that has something of the same transcendental quality.

They also happen to be spots where power lunchers already make reservations. Those are just going to be a little harder to get now.

Vaucluse at 100 E. 63rd St.

Vaucluse is fairly new in the New York City dining scene, having opened in fall 2015. A French restaurant from Chef Michael White, who is better known for Italian fare, boasts the added draw of a perfectly reimagined, two-dining-room space.

The location used to house another restaurant on this list, Park Avenue Summer, but White changed the tone into something bright and classic. Plus, the private dining space is killer.

American Cut Midtown at 109 E. 56th St.

A Tribeca hit, American Cut heads uptown. The Midtown dining room has been appropriately kicked up a notch for the power-dining set. The furniture says classic Gotham, but look at the art on the walls and you'll notice a grittier touch.

Milos at 125 W. 55th St.

Milos is known for being out of reach for most at dinnertime. At midday, though, the restaurant serves the lunch set with a reasonable prix fixe, which means you get to hang out in this epic dining room with all its natural light and high ceilings.

Summer is one of the most popular times of year to travel, but you can still find great deals on trips if you know where to look.

TripAdvisor just released the results of its annual TripIndex Cities study, which compares the cost of a three-night trip for two people across 39 popular tourist cities around the world.

To find the top 10 cheapest US destinations, TripAdvisor compared the cost of a three-night stay in a four-star hotel, a visit to three attractions each day, the cost of lunch and dinner each day, and the cost of two Uber or taxi rides of two miles each way per day. 

The prices for lunch (a meal and soft drink) and dinner (a starter, a main meal, and a bottle of wine to share) were collected from menus on restaurant websites. Transportation costs were based on prices from Uber and from local standard taxi rates. Attraction rates are based on the price of entry for the top five activities in each city, while hotel rates covered the average cost of a one night's stay in 4-star and 4.5-star hotels from June 2 through September 30 2016.

The "Happiest Place on Earth" just turned another year older.

July 17, 1955, Walt Disney and President Richard Nixon led the opening ceremonies in Anaheim, California. The park held just 18 attractions, and Sleeping Beauty's Castle wasn't even open to the public yet.

Today, the park hosts more than 16 million visitors annually.

To celebrate its recent birthday, we're taking a look back at how Disneyland came to be.

Walt Disney, pictured in 1950, wanted to build a family-friendly theme park across from his studios in Burbank, California, but local officials turned it down because they feared the carnival atmosphere would bring crime to the area.

Disney settled for 160 acres of orange groves in beautiful Anaheim, California. Construction began in 1954, just 12 months before the park's official opening.

The park cost $17.5 million to build. In order to finance the project, Disney partnered with ABC to produce a weekly one-hour program, titled "Disneyland."

It featured classic characters and fairy tales, documentary shorts on science and technology, and progress reports on the park's construction.

I was so excited when it arrived. I opened the box and was immediately enraptured by its sublime beauty.

It seemed as if this Rolex Explorer was made not of stainless steel, but some kind of unearthly metal. Quite simply, it felt like nothing I had ever held before. I found myself checking the time on the watch not because I needed to know, but just because I wanted to catch a glimpse of its face again.

I was sure that this gorgeous piece of horological perfection was going to rock my world.

But first impressions aren't everything, and infatuation eventually wears off.

As amazed as I was by the Rolex's hefty weight, incredible attention to detail, and pinpoint accuracy, I couldn't shake the feeling: I was wearing $6,000 on my wrist.

I didn't own the watch (it was a rental from the good folks at Eleven James, who let me try their service), but that didn't change things. I was conscious of it nearly all of the time. Walking down the street, riding the subway, shopping in stores, I was aware of the (surprisingly light) lug of metal and clockwork on my wrist. The guilt was immediate and unavoidable.

This stemmed from my foolish fear that people would notice it, and therefore treat me differently. This fear ended up being completely unfounded, as only one friend noticed it before I told them about it.

Only those with a keen eye for timepieces noticed what it was — pretty much everyone else completely ignored it, likely mistaking it for any other stainless steel watch and wristband. I'm pretty sure I got more comments on my usual Seiko 5, which I bought for just $60 on Amazon.

I realized nobody can really tell what you're wearing on your wrist unless you show them intentionally. And if you're wearing an expensive watch, do you really want to shout about it? If you bring it to the attention of anyone you don't know very well, you'll just look like a jerk.

I quickly realized that the only reason you should buy and wear an expensive watch is because you want to — not because you're trying to impress anyone. Unless you wheel and deal with watch aficionados, you're probably not going to.

When you're spending this kind of cash on yourself, you should be spending it for your own enjoyment. Don't wear a luxury watch for prestige and status because it's not going to work. The only ones who will notice and comment on it are already experts. And if you get to talking with them and don't know your Tourbillon from your chronograph, you'll look silly anyway.

When I strapped on the Rolex, I thought it was going to change my world. It didn't, but it did change my worldview.

No matter how much you loved your Mac when you bought it, chances are it doesn't perform the same way it once did.

And if you are currently trying to hang on for the next refresh of the MacBook Air or MacBook Pro, you might find yourself in need of a little performance boost. A few years can take a noticeable toll on any computer, but luckily there are some tips and tricks that can help bring it back up to speed.

Here are a few things to look out for that can make your overall Mac experience more smooth and efficient — without having to upgrade the hardware.

Reduce the number of apps that launch when you boot up.

If you have a bunch of different programs set to launch when you turn on your computer, it's going to take a while for your Mac to boot up. You can see exactly which apps are programmed to launch on start by clicking the Apple icon and navigating to System Preferences> Users and Groups> Login Items. In this list, you'll see all the items that start up with your computer. Check the boxes next to each app and click the minus button at the bottom of the window to remove them. 

Check for software updates.

Often, software updates fix bugs and glitches that could be slowing your computer down. Check for any software updates that may be available for the version of OS X your computer is running on. You can do this by clicking the Apple icon in the upper-left side and selecting App Store from the drop-down menu. In most cases, your Mac will probably issue a desktop notification to alert you when an update is available. 

Try restarting your computer.

It sounds obvious, but sometimes your laptop or desktop just needs a good restart to get back up to speed. Try restarting your computer before jumping ahead to other options. 

A night's stay in the penthouse suite at The Mark Hotel in New York City costs a staggering $75,000 (£57,000) per night, according to Elite Traveler.

The "shaving wars" between traditional cartridge slingers like Gillette and online startups who offer subscription models at lower prices is heating up. 

With the news that European consumer goods giant Unilever intends to purchase shaving start-up Dollar Shave Club, best known for its creative advertising and cheap razor cartridges, for $1 billion (according to Fortune) comes final definitive proof — shaving and personal grooming has successfully been disrupted.

The deal signals a dramatic shift for established companies like Unilever and Procter & Gamble (owner of Gillette). The companies are finally recognizing that more and more men are buying their shaving and grooming products online, and that this trend only increasing in pace, doubling to $263 million year over year in May of 2015 and surprising market experts, according to the Wall Street Journal.

Unilever gets more than just an entry into the shaving market for the first time with DSC, the WSJ notes. The unprofitable DSC does not make its own blades like competitors do, and in fact sources them from a company called Dorco, according to Lifehacker. It does, however, boast 3.2 million members and is on track to reach $200 million in revenue by the end of 2016, according to the press release on the acquisition. DSC will benefit from Unilever's global reach to bring its service to new markets as it continues to operate as an independent entity with CEO Michael Dubin at the head.

This puts pressure on Gillette, which is still the market leader with about 60% market share. P&G executives said privately to the WSJ that DSC's success caught the consumer goods giant off-guard.

Gillette started its own shaving subscription business in 2014 called The Gillette Shave Club to compete with DSC and fellow grooming startup Harry's. In the third quarter of 2015, it was reported by Fortune that Gillette's online business had grown to take up 21% of the ecommerce razor market, still paling to DSC's reported 54% share. Harry's makes up the lion's share of the remaining 25%.

In further evidence of the stakes at play and how seriously Gillette is taking its new competitors, in December of 2015 the company even sued DSC alleging patent infringement on the way certain materials coat and lubricate the razors

Though DSC wins in ecommerce market share, it's likely that Harry's is still the winner when it comes to net revenue. Its vertically integrated pipeline including a wholly-owned razor factory in Germany means it can manufacture better quality razors for cheaper for its more than 2 million customers and subscribers.

Prior to the sale, DSC and Harry's have both raised venture capital at $163 million and $287 million respectively, according to Crunchbase, with Harry's commanding a slightly higher valuation from investors at $750 million compared to DSC's $613 million.

For Harry's part in keeping up with the shaving wars, it launched on Tuesday its second generation razor blades with numerous improvements, as well as updated handles, for the same price as its old models. The DSC-Unilever deal will likely mean increased investor interest in the shaving brand.

With an aggressive Gillette, a Unilever-backed DSC, and Harry's vertical integration and design, the fight for which company gets the privilege to shave your beard as they fall out of fashion is on.

There's a new power couple in Los Angeles.

On Thursday, supermodel Miranda Kerr announced that she's engaged to Snapchat CEO Evan Spiegel — and to do it, she used Bitmojis from Bitstrips, which Snapchat just bought.

The Australian supermodel started dating the 26-year-old CEO a year ago. Here's how the two fell so quickly for each other:

Taking a long trip can occasionally feel like playing Russian Roulette with my body. Sometimes I recover quickly and barely seem to notice the time difference, and other times I'm exhausted for days.

No matter how long it lasts, jet lag is never fun, and researchers still haven't found a "cure" for the bothersome side-effect.

But they have uncovered a new piece of the puzzle about what causes jet lag — and it could help ease the pain of your next globe trot.

It turns out that our internal clocks are a bit laggy — they run a tad longer than 24 hours. That makes westward travel easier, since it involves simply adjusting to a slightly longer day. Traveling east, on the other hand, is much tougher for the body to handle. So what's the best way to help convince your internal time-keeper (local time: confused o'clock) to run on the same schedule as your external clock, or the local time at your destination? Sunlight.

To get a closer look at what's going on in our bodies when we travel, scientists recently experimented with the "master clock" cells, located deep inside the brain, that play a role in helping our bodies keep track of time.

What they found confirmed what several studies have suggested for years: molecules on these cells interact with other molecules throughout the body to keep our biological clocks running smoothly. Several genes (along with the proteins they make) also play a role in keeping these internal clocks ticking.

But how do these molecules know what time it is? They get information from our environment, including how light or dark our surroundings are. The lighter and brighter it is, the earlier it is; the darker it is, the later it is.

When we travel long distances, our bodies don't get the input they need to tell time. That confuses our internal clocks, which also tend to run a few minutes longer than 24 hours. Put these two factors together — no daylight cues + laggy internal clocks — and you've got a recipe for jet lag.

But it turns out that jet lag is much worse for one kind of trip: those that involve traveling east. Why? Because when we travel east, we have to set our (slow) internal clocks earlier and cut our days short. Conversely, when we travel west, we simply set them later and deal with a slightly longer day. Studies suggest that we can convince our internal clocks it's about two hours later each day but we can only convince them it's about 1 to 1.5 hours earlier each day.

While 30 minutes to an hour may not seem like much, it can have some pretty big effects if you're crossing multiple time zones. 

That's why the best way to address the problem and make your jet lag misery as brief as possible involves matching your biological clock to the local time of your destination as quickly as possible. One of the best ways to do this is to get lots of sunlight in your destination, which tells your body it's time to stay awake! "Natural light exposure is the ideal mechanism for counteracting jet lag," the authors of a 2011 study in the journal Pharmacy and Therapeutics write.

This can be tough to do when you get off a long flight mid-day and feel exhausted, but the effects will probably be worth it. If you're in a new place, try exploring by taking a walk outside. If your traveling for work, take your work where it's sunny. Your body will thank you.
