Cross-country skiing has an image problem. It’s less glamorous than downhill, less showy than snowboarding. Even at the Winter Olympics the sport, also called Nordic skiing, doesn’t get much respect. But enthusiasts know it’s a great workout. Because cross-country exercises the large muscle groups in both the upper and lower body, it can boost oxygen-uptake capacity, or the amount of blood the heart pumps in a single beat. (Elite Nordic skiers are the kings of oxygen uptake; marathon runners are second.) Gliding along at a moderate clip, you can burn 800 calories per hour, nearly twice the rate of downhill skiers. The sport’s also safer than Alpine skiing. And fans say the peaceful pastime is more than just a workout. “Skiing in a quiet area… is very spiritual,” says Hermann.

Begin at a cross-country touring center ($10 to $15 a day for trail fees), where you can rent equipment and get a lesson. If you get hooked, you can outfit yourself for about a third of what you’d pay for downhill gear–about $130 for good boots and $150 for skis. Clothing should be layered–start with a material that wicks sweat from the skin. Add wind pants, a fleece jacket and a waterproof shell, if needed. Don’t forget your shades.
