The sport first began in the United States in the 1980's and its origins can be traced（探寻）directly to two other sports: roller-skating and ice-skating. For people who have never tried it, roller-blading looks difficult. But the truth is it only takes a few hours and a bit of courage to get started. If you talk to people who can roller-blade, they will tell you the two most important things to remember when you start are to be brave and persistent（持久的）.

　　The first few times you try, make sure you wear all your protective padding and just go slow. You will be surprised at how quickly you can learn. Once you get going, you will notice how much exercise your legs and hips will receive. Eventually, you will develop extra muscle strength in these areas and lose some of the extra weight you might have been carrying. There's no doubt your overall fitness will improve.

　　Roller-blading is a popular sport but it is also a practical way of transport. If you usually ride a bicycle, or walk to school or work, then perhaps you can start going by roller-blades instead. But most of all, roller-blading is about having fun. There's nothing better than putting on your roller-blades and gliding（滑行）around a lake or a park on a sunny day.
