The Bod Pod® is used in scientific journal studies to accurately measure body fat percentage and fat free mass, which is a key predictor of your metabolism, health, vitality and performance. Learn if you have the right fat free mass to meet your goals. After two 40-second measurements in the Bod Pod, your fitness expert will interpret your results and calculate your ideal body weight for health, fitness or performance. For accurate results: No heavy meals or vigorous exercise 60 minutes prior to testing. Bring minimal clothing to wear during Bod Pod testing (women, bathing suit or sports bra and tight-fitting shorts or capri leggings; men, tight-fitting bathing suit – no board shorts – or tight-fitting underwear).
