Although not often thought of as a common form of cardio, ascending walls is a sure way to get your heart pumping, similar to the way climbing stairs or jogging does. A one-hour climb session can burn well over 700 calories . Plus, tricky maneuvers and lengthy reaches often require developing flexibility that wasn't there before.

When magma cools at the surface, it cools rapidly and does not have time to form very large crystals. Basalt, found on the ocean floor, is an example of an extrusive igneous rock. On the other hand, magma that cools slowly beneath the Earth's surface forms rocks that contain large crystals. Geologists refer to these as intrusive igneous rocks; granite is an example of an intrusive igneous rock.
