Do you spend your summer seeking outdoor adventures? Mountain biking on rugged trails or scaling the face of a rocky mountain? While opportunities for your favorite outdoor adventures may not be so numerous in winter, you can still get your adrenaline rush indoors.

Men's Health shares four amazing indoor adventure sports centers across the country. But you may be able to find something a little closer to home. For example, in my neck of the woods there's an awesome rock climbing wall at the community center, a rowing pool at a local rowing club, and an indoor skating/biking facility just a couple hours away.

And don't forget about all the incredible adventure sports -- such as snowboarding and skiing -- winter has to offer as well. AOL Health has 11 fun winter fitness activities to try.
