On Wall Street, on the sixth floor of the Gild Hall hotel, I’m standing in perhaps the smallest gym in New York City, a “fitness center” hardly bigger than a walk-in closet. It’s standard-issue hotel fare—spare white walls and a concrete floor, outfitted with only a single treadmill and a StairMaster. But for the guy I’m with, we may as well be in a fully stocked Crunch.
His name is Chris Jordan, and he’s the director of exercise physiology at Johnson & Johnson’s Human Performance Institute, based in Orlando, FL. He’s visiting New York to give a series of talks about the science of exercise, and he’s taken me here to show me that rooms like this have everything I need to achieve a fat-shredding, full-body workout. In fact, we’ve got more than enough, he says, because we don’t even need the machines. Jordan is the man behind Johnson & Johnson’s Official 7-Minute Workout exercise app, which guides users—typically working professionals on the go—through a quick succession of high-intensity body-weight bursts; last year it became one of Apple’s top downloaded Health & Fitness apps, and it’s remained one ever since.
