By now you've heard plenty about how bad sitting is for our health. And a recent study has shed even more light on why we really do need to sit less and move more.

In fact, these researchers found that sitting for fewer than three hours a day can add up to two years to your lifespan.

For many people, the big obstacle is work. Anyone with a desk job knows all too well how tricky it can be to tear yourself away. And people in a number of other professions -- like truck and bus drivers, for example -- really have no alternative.

Luckily, the weekend presents an opportunity to make up for lost time. Instead of spending your days off on the couch, here are some of our favorite ways to move more this weekend. (Calorie counts are based on a 150-pound person as estimated by MyFitnessPal.)

  • Stand At The Bar

    Rather than nursing a drink sitting down, belly up to the bar, or grab dinner at a high table with bar stools. <a href="http://www.health.com/health/gallery/0,,20534367_4,00.html" target="_hplink">Leaning against a high stool</a> is a step up from sitting, but can be more comfy than standing all night, <em>Health</em> magazine reported.

  • Mini Golf

    This old-timey favorite is fun for kids and adults alike, and can burn 100 calories in just 30 minutes. <em>Flickr photo by <a href="http://www.flickr.com/photos/machineisorganic/6740536715/" target="_hplink">Machine is Organic</a></em>

  • Take A Swim

    You don't have to be Michael Phelps to get a water workout. Even some leisurely splashing around can shave off 200 calories, and it's a great way to stay cool in the heat, too! <em>Flickr photo by <a href="http://www.flickr.com/photos/joeshlabotnik/311692139/" target="_hplink">Joe Shlabotnik</a></em>

  • Build A Sand Castle

    Instead of just lounging on the sand working on your tan, get up and move around if you're at the beach this weekend. Bonus: Digging in the sand can be a surprisingly <a href="http://www.webmd.com/fitness-exercise/features/great-summer-workouts?page=3" target="_hplink">good workout for abs and obliques</a>. <em>Flickr photo by <a href="http://www.flickr.com/photos/donhomer/7200149722/" target="_hplink">Michael Bentley</a></em>

  • Dance

    Let the music move you when you're out on Saturday night. A little boogying can burn 150 calories in just 30 minutes.

  • Throw A Frisbee

    You're not chained to that park bench! If you're already enjoying the outdoors, why not throw around a Frisbee or a football, pass a volleyball or kick a soccer ball? It doesn't have to be strenuous -- you don't even have to be any good! -- but it will get you up and moving. <em>Flickr photo by <a href="http://www.flickr.com/photos/perspective/458811240/" target="_hplink">Elvert Barnes</a></em>

  • Go On An Exercise Date

    If you've got a date night planned this weekend, skip dinner and a movie in favor of something that gets you off your rears. It doesn't have to be a trip to the gym or a jog -- it can be anything active you like doing together. <em>Flickr photo by <a href="http://www.flickr.com/photos/78428166@N00/7283892652/" target="_hplink">Tobyotter</a></em>

  • Row A Boat

    Many local parks, rivers and lakes have row boats, canoes or kayaks available for rent. No matter your vessel of choice, it's a fun, seasonal way to burn some serious calories. <em>Flickr photo by <a href="http://www.flickr.com/photos/inner-eye-photo/6849944748/" target="_hplink">Josh Hawley</a></em>

  • Play Fetch

    During the busy week, you sometimes might just let your pet out in the backyard to dig up his own trouble. This weekend, spend a little extra time moving with him. Play fetch, give him that much-needed belly rub or take him on an extra-long walk. <em>Flickr photo by <a href="http://www.flickr.com/photos/footloosiety/4255290603/" target="_hplink">footloosiety</a></em>

  • Catch Up On A Walk

    If you've made plans to meet a friend for coffee, take your catch up session to-go instead and gab on a walk. Even strolling at a snail's pace will burn 85 calories in 30 minutes!

  • Play Bar Games

    Put down the drink for some foosball or pool if you're at a bar this weekend that offers it. Thirty minutes of pool can shave off 85 calories, not to mention you may save yourself a few if your hands aren't wrapped tightly around that pint glass. <em>Flickr photo by <a href="http://www.flickr.com/photos/15216811@N06/5842783313/" target="_hplink">Nicola since 1972</a></em>

  • Take A Hike

    Head for the hills! Depending on where you live, a hike can be a weekend expedition or a quick afternoon adventure. It's a change of scenery and a great way to spend some time outdoors. If you're feeling sporty enough to tackle some hills, you can burn almost 250 calories in just 30 minutes. <em>Flickr photo by <a href="http://www.flickr.com/photos/mikebaird/4104101152/" target="_hplink">mikebaird</a></em>

  • Go Cab-Free

    If you typically find yourself hailing a taxi on the weekends, try hoofing it instead. If your destination is too far to make it on foot, try public transportation -- and leave the seat for someone else. <em>Flickr photo by <a href="http://www.flickr.com/photos/tmab2003/3180940701/" target="_hplink">TMAB2003</a></em>

  • Play Lawn Games

  • Go Window Shopping

    Those people who do their exercise walking around the mall are onto something. Whether or not you plan to buy anything, browsing around your favorite shopping center gets you moving -- especially if you decide to wiggle in and out of a few things in the dressing room. <em>Flickr photo by <a href="http://www.flickr.com/photos/jimmyharris/2774384836/" target="_hplink">jimmyharris</a></em>
