When did skiing become a sport?
The first skiing competition was held in January 1862 by "Trysil Skytte- og Skiløberforening" in Norway.
It depends what kind.....Cross-country skiing at a good pace (generally on a rolling hills terrain to very hilly) is proven to be the best sport for you. Skate-skiing works nearly every muscle!! Downhill skiing on the other hand is a leisurely and pointless sport if you are looking to get fit!!! Downhill skiing is not bad for you(but you could injure yourself)
