Start off by riding your bikes this weekend, just like in this scene from Mamma Mia! Here We Go Again. Nothing beats the feeling of wind in your hair, especially when you've been inside for days on end. And if you happen to break into song? So be it.
Inspired by Whip It!, dust off your old pair of roller skates (or get new ones) and spend the day gliding down the sidewalk together. Keep practicing until you can do tricks, or at least stay upright for more than two seconds.
If you can find a zipline course open near you, spend the day flying through the sky, à la pretty much every character in Girl's Trip. (Hopefully you won't get stuck midway, but if you do, it'll at least make for a funny story.)
Recreate the quaint camping scenes from Moonrise Kingdom by heading out into the woods (or your yard) with all the comforts of home. Bring a record player, cool outfits, and lots of books. But most importantly, just enjoy being outside.
Tear a page from Superbad and decide right now that you're going to stay up all night, no matter what. Because when you have nothing else to do, silly challenges like this one can make for a super fun date.
Let Amélie inspire you to enjoy your city with fresh eyes. Even though you can't travel somewhere far away right now, there's likely a ton you've yet to appreciate within a five mile radius. Visit parks, take photos, and see what adventures you can get into.
For a different take on adventure, consider getting a tattoo, like Pete Davidson's character in The King of Staten Island. Or for something a little less intense, get second ear piercings, or make like everyone else in quarantine and dye each other's hair.
While you don't have to cook 524 recipes, like Julie did in Julie & Julia, you and your partner can flip through a cookbook at random, and vow to make whatever you land on — however difficult or gourmet it might be.
You might not be able to get your hands on an amazingly retro Volkswagon van, like the one in Little Miss Sunshine, but you can still have a good time road tripping together. Set out sans plans, and trust that cool things will happen along the way.
If you're craving some exercise, why not spend an afternoon learning a new sport together? Pull up a few YouTube tutorials and practice the basics of ballet, like in Center Stage, soccer like in Bend It Like Beckham, or even boxing, like in Million Dollar Baby.
Did you just watch Palm Springs and love it? While I don't recommend getting caught in a Groundhog's Day-type time warp, let it inspire you to romantically float in a pool together with drinks in hand. Because sometimes, that's all the adventure you need.
