It's a lot less expensive than downhill skiing—all you need are the skis and a flat, snowy trail. But you can get the same benefits any time of year with a home Nordic or cross-country ski machine when you work your arms and legs simultaneously. This upper-and-lower body workout is also low-impact, meaning minimal stress on your joints.

The ski machine is designed to simulate cross-country skiing, a sport that requires full-body engagement to propel oneself forward on snow. As a result, using the ski machine can provide a full-body workout that engages your legs, arms, core, and back.
