Getting Fit in Your 20s

I would definitely say Cross-Country Skiining if you have enough snow! I started a couple of years ago and LOVE it! Plus it's cheap. And you don't need tons of athletic skill to do it. I mean if you want to do it well then there is a definite technique to it, but it's a fabulous workout - you get outside - and boy oh boy do you work up a sweat!

Check around - I know when I started I would just rent the equipment for a weekend for about $25. That way you can see if you like it or not!
