Fresh, funky & fast
Next Sunday marks the 16th Standard Chartered Hong Kong marathon. A total of 70,000 people have signed up to compete in the 10km, half (21km) and full (42km) races. Marathons have become many people's get-fit plan of choice in recent years, with many teens competing, too.
But if running long distances - or running at all - isn't your thing, don't worry: there are plenty of other hip ways to get your heart pumping in the year of the dragon.
Capoeira
Capoeira is a Brazilian martial art which is said to have developed by slaves in 16th-century Brazil. The slaves would try to escape, but they could not match the Portuguese colonists' weapons or knowledge of the land. They started to work on a method of survival for if and when they did manage to escape.
Modern capoeira is usually less of a battle, and more a dance-like practice of the skills required. The most common moves include cartwheels and kicks, all set against a driving rhythmic background of drums and traditional instruments.
Zumba
Alberto 'Beto' Perez probably never imagined a simple mistake would start a global phenomenon. Heading out to teach a class, the dance instructor realised he'd left his cassette tape at home. He grabbed a random one from his car, improvised what he taught in class, and created Zumba, a Latin dance-inspired fitness programme.
Rock climbing
Ultimate Frisbee
Forget what you think you know about frisbee. It's not just about throwing and catching. Ultimate Frisbee, aka Ultimate, requires you to run back and forth on a field and score like a NFL player. According to figures published by CNBC, the sport, which was developed by high school students in 1968, was already played by 4.9 millions Americans in 2008.
Ice hockey
If you want to feel what it's like to move the speed of light - but can't drive a Ferrari, let alone afford one - what you need is a pair of inline skates. You may think ice hockey belongs only to snow-buried countries like Canada and Russia. But thanks to modern technology, you can play in shopping malls in Hong Kong.
Before you start scoring goals, you have to know how to skate. You can enrol in lessons (check out the little shop which usually sits next to every skating rink's entrance), or teach yourself with a copy of Ice Skating for Dummies and a lot of practice.
Whether you take up a new sport this year, or continue to improve your skills in an old favourite, may your 2012 be super-fit.
