You won't be using it to train for the World's Strongest Man competition, but if all you're looking for is enough weight to keep tone while you're sitting at your desk, the Alias Barbell ($150-$200) is all you need. Available in 1kg (2.2lbs) or 2kg (4.4lbs) varieties, these sleek fitness implements are made from chromed casting brass, and feature thermoplastic rubber on the ends to keep your desk — and the weight — from getting scratched up. Designed by the one and only Philippe Starck.
