Jason Serafino has been a writer and editor since 2012 and has held various roles at Complex, Mental Floss, Muscle & Fitness, and more. When he’s not working, he's usually at the gym (before 7 a.m.), at the park taking orders from his dog, or slowly getting through a pile of unread books that he knows he’ll never actually finish. He’s also proud to (probably) be the only person with a tattoo of Teddy Roosevelt and the Ultimate Warrior on the same arm.
