Rowing is an exercise that provides both cardiovascular and strength conditioning. The constant upper-body movement gets your heart pumping and provides an intense calorie-burning workout. In addition, major muscles in your upper and lower body are utilized through the resistance of the exercise. Rowing works muscles in your back, arms, shoulders, legs and hips. Rowing also promotes stabilization throughout the torso.

As with most exercise, using good form on a rower will get you better results.

To get the thigh-toning benefits, make sure that you are pushing off with your legs (your arms shouldn't do all of the work). To tone your arm muscles, keep your elbows close to your body. And to avoid back strain, don't curve your back.
