When
rowing on the WaterRower you use a massive 84% of your muscle mass. Other
common aerobic exercise equipment such as treadmills, cycles, ellipticals
and even other rowing machines, use far less muscle mass, burn fewer
calories and generating less exercise benefit.
The Oarsperson utilizes the
various muscle groups in proportion to their strength, generating a uniform
aerobic load over all muscle groups. A workout at 80% intensity produces an
aerobic load of 80% in the muscles of the arms, 80% in the muscles of the
torso and 80% in the muscles of the legs. In this way rowing recruits the
muscle groups uniformly and proportionally to their strength, optimizing the
exercise benefit derived given the fatigue limits of the muscles.
Many so called whole body
exercises (and indeed many conventional rowing machines) load the muscle
groups disproportional, hence the limits of the exercise done are the
fatigue limits of the most heavily loaded muscle groups.
