Cross-country skiing is a premiker, low-impact full-body cardiovascular workoiut that burns high levels of calories (up to 355 in 30 minutes for a 185-pound perdson) while engaging over 600 muscles.

The machine mimics the motions of cross country skiing. Your arms pull on tension mounted strings while your legs push against an adjustable level of tension. The incline can be increased to put an emphasis on quadriceps rather than hamstrings.

It folds down completely and has rear wheels for easy transport and storage.
