Brrrr...it's cold out there. No, this isn't the start to that famous early 2000 cheerleader romcom chant from Bring it On. No it really it's cold outside. We might be in the middle of a late winter, but the late season snow and below freezing temps are making up the difference. Unless you're an avid skier or snowboarder, going outdoors for exercise between the months of November and early April is not an option.
