The technicians at DexaFit use dual-energy X-ray absorpitometry (DXA) to take a highly detailed inventory of their clients' lean muscle, body fat, and bone mass. They then use the data to build scientific, tailor-made fitness and nutrition routines. More accurate than submerging the body in a tank of water or vat of ranch dressing to measure displacement, DXA technology offers specific data on regions such as the legs, arms, and trunk. With 98% accuracy, they perform body fat testing, lean mass analysis, and bone density screening. The info helps clients figure out where they store fat and build muscle, and helps improve their metabolic rate.
