"It's also important to vary your stimuli. I always look for new things to shock the system. Just as you make muscles grow by shocking them, you make the mind grow by shocking it."

In this case, "exo" is short for exoskeleton, a powered suit that provides added strength. Since this is a William Gibson work, I'm betting that this is no clumsy robotic "Transformers" style device; it is probably a great-looking suit. Note also that carbon fibers are long and strong; but then, so is chitin, the main structural ingredient in arthropod exoskeletons.
| She could hear their voices, from where she sat in living room, their laughter. One of the assistants was a girl in a blue polycarbon exo that allowed her to carry the Hermes wardrobe cases as though they were weightless blocks of foam, the humming skeleton suit padding softly down the stairs on its blunt dinosaur feet. Blue skeleton, leather coffins. Now Porphyre stood in the doorway. "Missy ready?" He wore a long, loose coat cut from tissue thin black leather; rhinestone spurs glittering above the heels of black patent boots. |

The notion of an exoskeleton is derived from biology; many of the world's creatures have no backbone, but use a hard outer shell. It is an elegant solution, since it combines protection with the same structural purpose of bones.
The idea of an exoskeleton has been used before in science fiction; for example, the soldiers in Robert Heinlein's Starship Troopers achieve parity with the insect race they fight by using military exoskeletons (see powered suit).
Why do we assume that an exoskeleton will make you stronger? It is true that some arthropods can carry up to 50 times their body weight. Also, having muscles inside an external skeleton is more efficient. However, most of the advantage comes from the fact that they are small; their muscle weight is low compared to muscle surface area.
