(WGN) -- LAKE BLUFF, Ill. - It's that time of year when people are considering their New Year's resolutions and goals for 2025. In north suburban Lake Bluff, one man is about to accomplish a goal he set 10 years ago. If you ever find yourself between a rock and a hard place, let Kevin Cullum be your inspiration to push past your problems. “With enough time, energy and effort, anyone can do anything in life," he said. Cullum is just days away from finishing a decade-long fitness challenge - one million pushups. ‘Just go out and do something:’ 59-year-old Chicago grandpa inspires millions to get fit "I've been working since 2015 to do one million pushups," Cullum said. The number is so big that it seems out of this world. "The amount of up and down space I've done over the years is something like to the moon and halfway back," Cullum said. After all, fitness challenges typically cover days, but this one lasted a decade. "A big part of the whole thing I'm trying to do is to show that good things don't happen quickly," Cullum said. While in his mid-20s, Cullum had debilitating anxiety and started doing pushups as a way to sooth himself. "I've always battles internally with mental struggles and demons and just anxiety," he said. However, the physical activity and focus improved his mental outlook. Cullum said he's recorded every single pushup he's done, starting all the way back to his first one from January of 2015. The pushups are logged in a notebook and then on his computer. Long-lost blueprints show Chicago Stadium’s enduring significance "After a couple of years, it dawned on me that I had done a lot of pushups," Cullum said. "So here's the Google Doc that I created years and years ago. I track every date, every year down in their own tabs." The most pushups he's ever done in one day is 3,000. The pushup challenge became not only a test of strength, but also endurance. Along the way, Cullum gained a large following. He has over 110,000 followers on Instagram who watch him push himself off the floor, the driveway and many more memorable locations. "I've done them in my car while going through a car wash; I've done them in Notre Dame Stadium; I've done them in Wrigley Field; I've done them on top of my car; I've done them in restaurants, in bars, in the lake, when it's cold outside in the middle of winter," Cullum said. He also uses social media to deliver inspirational messages to the masses. One video on Instagram shows Cullum, a father of two, disappearing behind the couch in his kids' playroom, logging pushups while crouched at a tea party table. He'll also crank out sets while working at his dining room table. "I'll do work while I'm doing it; I'll fold laundry; I'll play with my kids, do stuff around the house and get down and do sets of 15 until I get to a number I'm content with," Cullum said. "It's usually like 500 (pushups) or so a day, and I take days off. I don't do them every day."

One bite at a time. "That is the point - to show people if you want to go get something in life, it's going to take a while. Don't quit and eventually you'll get there," Cullum said. He serves as an inspiration and living proof that anyone can accomplish anything. If you realize when you're between that rock and that hard place, it'll all eventually work out. "You're going top be alright, man. You're going to find a way," Cullum said. He will complete his one millionth pushup on Sunday, Dec. 29 - the day of his parents' 40th wedding anniversary - giving the family two nice round numbers to celebrate.
