January is now well underway and if you're still struggling with all the extra weight you put on over Christmas, or you've not yet made a start on your new year's resolution to get into shape, then taking a trip to London could provide the perfect opportunity to start leading a more active lifestyle.
That's because the capital is full of great places where you can get some fresh air and exercise while also enjoying the sights of the city, so it really won't feel like a chore at all.
Taking a bike ride along the banks of the Thames, for example, is a fantastic alternative to public transport, and with a special Cultural Cycling Tour route having been created for tourists to follow, it's now easier than ever to take in all the major attractions and get your heart pumping at the same time.
Running all the way from the South Bank to Greenwich, before looping round to pass by Canary Wharf and then Tower Bridge, this is a truly excellent way to experience London, and you'll feel all the better for your workout once you've finished.
With Boris Bikes available for free across the city, you won't even need to worry about bringing your own bicycle with you to the capital, so there really is no excuse not to have a go at this fantastic two-wheeled adventure.
Of course, if you'd rather run than pedal then you'll find loads of great places for a jog, with London being home to more green space than almost any other capital city in the world.
Hyde Park, for example, is a terrific place to stretch your legs, and when doing so you'll be able to enjoy some wonderful sights such Kensington Palace Gardens and the Serpentine boating lake.
Regent's Park is also popular among joggers, and if you take a route that follows the Regent's Canal then you'll be able to feast your eyes on the many birds that live in the London Zoo aviary, which overlooks the canal itself.
