Stuck in a cardio rut? Here’s something new for your favorite elliptical: Keep that heart pumping by transforming your everyday elliptical session into a cross-country skiing adventure. To simulate the strenuous gait (and burn) of cross-country skiing, lower the incline on your elliptical, set resistance to mid-range, and vigorously add your arms and upper body to the workout. Renowned as an ideal cross-training activity for runners and cyclists, cross country skiing (be it the actual sport or simulated on your elliptical) works wonders on your glutes, quads, hamstrings, calves, chest, lats, shoulders, biceps, triceps and abs.
