The new year: a time for renewal, regeneration and, of course, a sincere apology to your internal organs for a decidedly decadent December. Which is why the theme for this week's issue is fitness. Not that you need to be reminded of the importance of worshipping at the gym's altar, but staying in shape doesn't always have to involve the pumping of iron in a windowless room full of men. Here, we've picked a selection of goodies from the techno-sphere that you can keep on your person, just in case the need for an impromptu training session suddenly overcomes you. Oh, and of course, we'll also help to make you look effortlessly stylish while you're at it.
