At a Glance

The Tanita RD-953 is the body composition monitor of choice for serious athletes, sports scientists, and performance coaches. Its 8-electrode BIA system measures fat and muscle mass in each body segment separately — right arm, left arm, right leg, left leg, and trunk — allowing identification of strength and hypertrophy imbalances that bilateral measurements miss. Muscle quality score (ratio of muscle mass to body weight per segment) is a unique metric found only in professional devices. Used by Olympic training centers worldwide.
