Finally, an exercise ball that doesn’t look like something the chiropractor dragged in! With one of these pebble-chamois numbers from Material Possessions ($198 for a 72-inch ball, $308 for a 100-inch ball), strengthening your core no longer has to wreak havoc on your dé-cor (good one, huh?). They’re no Barcelona chair, but certainly  attractive enough to sit nicely in a corner without offending anyone. Now what can we do about those stationary bikes?
