Ride your bike

Bikes outnumber people (at 18 million versus 16,5 million) in the Netherlands.

• 40 percent of the Dutch use their bikes for commuting.

• Traffic lights in some parts of Amsterdam are even synchronized to bike speed.

• Riding bikes in good weather for errands, work or pleasure can help fend off weight gain.

• "Casual riding for errands and commuting can burn around 500 calories an hour, but if you up the exertion or add in hill-climbing, you can burn up to 1 1 000 calories an hour," says Stephen Cheung, an exercise physiologist at Brock University.
