If you're body image obsessed, Tanita's new BC-558 scale — they like to call it the "Ironman Segmental Body Composition Monitor" — will allow you not only to weigh your entire carcas but to take separate body mass readings for each limb. It uses bioelectrical impedance analysis just like most scales with body mass features, but multiple electrodes, including two in retractable handgrips, let you freak out that you're not only fat, but asymmetrically chubby.
The scale costs $300. Consider this one for professional bodybuilders only.
