On the outskirts of Nike‘s yawning campus in Beaverton, Oregon, a nondescript garage sits behind a line of tall trees, hiding between a day-care center and a security firm. A door to the garage, marked only with the letter “A,” is always locked; the windows to the facility are tinted like a rapper’s SUV. Inside, two toned athletes are lunging in front of a pair of Xboxes. A gaggle of laptops tracks their progress, spitting out Matrix-like data onto the screens. The floor plates beneath their feet are pressure-sensitive. There are high-speed cameras and infrared lights watching overhead, staring down at various weight machines, climbing ropes, and other gym props.
