Athletes Pose Nude For Sport Calendar 2018

The start of the new year always guarantees a few things: An insanely long line's about to form at your gym's squat rack, and you're going to need a new calendar. And to ring in 2018, the Sport Calendar 2018 is serving up some serious workout inspiration that will make you kick your fitness resolutions into high gear.

A group of 18 athletes ranging from boxers, basketball pros, CrossFitters, Olympians, and more bared it all to help keep you a little more organized next year. Available in both a women's and men's edition, the book isn't just your typical wall calendar or day planner. It includes a Training box so you don't have to carry around an extra notebook when you hit the gym, as well as circles to fill in for the amount of sleep you got that day.

But the photos aren't just so the fit group can show off their time well spent training in and out of the weight room, or so they can pose while jumping on trampolines for the hell of it—it's also for a great cause. When someone buys the calendar, the proceeds help support the charity One Year Fund, a "fund to support young athletes," according to its site.

"We reach out to the best and brightest, help them stay on their chosen path, and motivate them in achieving their goals," the photographer behind the Sport Calendar and CEO of One Year Fund, Dominika Cuda, said, according to the Daily Mail.

If that wasn't reason enough to pick up a new planner for next year, we don't know what is. Another bonus: Now you might actually pay attention to that thing you penciled in on the 18th. And if you won't be able to make it to Poland to buy one, you can pick up one of the planners here for around $36.
