Day continued to battle chronic back pain in 2019. After a decade of dealing with the problem, he was not afraid to try new remedies. "I was explaining the other day that I was blowing into balloons," Day told reporters at Quail Hollow in May 2019. "Which is crazy, because I haven't really trained at all this year because I've been so sore." The balloon therapy, which takes about 20–30 minutes twice a day, is supposed to help get his rib cage, hips and shoulders aligned, thereby alleviating pressure on his back. "Blowing into balloons, that's as far as I go," he said of the therapy. "Long story short, I try to keep my rib cage down. My rib cage gets up and then it blocks my mid back and then I can't really turn. So I get it from somewhere else and that's why my back flares up."
