Mantras are memorable words or slogans repeated over and over to point one’s thoughts in a positive direction. As I do my treadmill routine each morning, I reflect on key words. These words focus my mind, allowing me to maximize my energy. I asked Jay and Emma–one a ski instructor, the other a competitor in Cheer–to participate in a film version of the treadmill mantra. It’s the first project I’ve shot on a cellphone.
