When we were kids, we couldn't wait for school to let out so we could spend the whole summer outside playing with our friends. Now that we’re older, when we’re not in school, we’re usually working. Thankfully, most of us have not yet reached the point where we’re totally consumed in stressful work, long hours, and no time for fun. So when we do have a day or two away from our jobs, how should we fill the time? 

So far, your summer has probably consisted of bumming on the beach, or by the pool, or binge-watching your favorite shows on Netflix. I, for example, have already re-watched all 121 episodes of Gossip Girl. Instead of lying around all summer, indoors or outdoors, here are six sports that you absolutely must try this summer. 

1. Stand up paddle boarding. SUP has exploded in the last year. Unlike some of its outdoor fad counterparts, this has the potential to be a long-lived craze. Not only is it a great workout for your core, arms, back, shoulders, and quads, but you’re burning 420 calories an hour in this fun and social workout. Next time you’re on the water with friends, grab a board and race up the creek. Most water-sport outfitters have rentals, if not guided tours and lessons.

2. Ultimate Frisbee. This intense sport is nothing like throwing the disc while Spot fetches. Gather some friends for a pickup game -- it only takes seven to form a team -- or get more serious and join a league. There are ultimate organizations all over the country, so find your local group and get involved. 

3. Kayaking. Kayaking is an incredible workout for your upper body and core. The average kayaker burns around 330 calories per hour and even more with a higher level of intensity. It’s a great way to work your muscles while enjoying the scenery.

4. Surfing. This one is going to take a bit more practice, but good news! You don’t have to be able to swim like Michael Phelps to rock at surfing. The board itself doubles as a flotation device! If you've 
never surfed before, try it out on a long board for better balance. And if you can find an instructor who looks like Eric Geiselman, you've got some added motivation. 

5. Hiking. This is an excellent way to work your legs and glutes this summer without setting foot on a stair master, thank God! Hiking burns up to 400 calories an hour and can turn into a great outdoor adventure. Beginners should stick to areas they’re familiar with or well-marked trails. Tons of water is essential, and it’s not a bad idea to wear long sleeves and pants to avoid dangerous bugs and plants.  

6. Beach volleyball.

 You've been keeping in shape all summer, and it’s time to show off your new bikini bod. What better way than a battle of the sexes in a beach volleyball tourney? Bonus points if you find a court that backs up to a beach bar so you can cool down with a cocktail after beating the boys! 

However you decide to spend the remains of your summer, don’t let it pass you by. Be proactive and have some fun. Netflix can wait for when you need to do some serious procrastinating before midterms in the fall. There’s nothing worse than a bad case of FOMO when you start seeing your friends’ Insta adventures. Why not be the friend everyone is jealous of? Someone’s gotta fill that role, and it might as well be you!
