These creative 12 days of Fit-mas fitness challenges from Constantly Varied Gear are one way to celebrate the season. Each day, they share a little video to inspire you to get moving. We’re not affiliated with their giveaway, but we thought this was a cute idea. Of course, you can expect to do planks, burpees, and squats, but there are a few partner challenges, too. We can’t wait to grab a sneaker and try the challenge on Day 5. And if you have a bar to hang from and a friend, try the tank-top challenge on Day 8.
