Fuel your progress.

Don't let any sweat go to waste; train more efficiently by taking control of your weight loss. From building muscle to boosting metabolism, see how your body is changing and what to adjust.

A higher bar of accuracy:
bioimpedance analysis, at two frequencies.

Standard BIA: current runs up the legs only and flows around cells

4 electrodes. One low frequency.
The standard scale with limited reach.

Most household scales consist of just a footplate, and four electrodes that emit currents at one low frequency. For many, this system is enough to get the job done. Not for athletes in the making, though. No direct path to the arms and torso means uneven coverage, and blind spots everywhere. Upper body reads end up coming down to guesstimates.

DF-BIA: current runs hand to foot and passes through cells as well as around them

8 electrodes. A dual-frequency system.
The high-low setup that leaves no gaps.

The body scanning game changes when a whole new frequency comes into play, and an electrode-decked handle gets added to the mix. Direct insight into each body part's fat and muscle balance no longer has to rely on low-frequency currents measuring around cell walls, and guessing what lies within; high-frequency currents can penetrate through and cover what a lower frequency can't reach. Guesswork stays out of the equation, and what remains is a far more defined picture of your body.

A scale for results. An app for insights.
FITINDEX Pro for the whole picture.

8-electrode system with built-in handle

Four electrodes on the foot panel and four in the built-in handle create a full foot-to-hand measurement path, enabling more direct segmental analysis and more stable readings.

Powered by DF-BIA

Dual Frequency Bioelectrical Impedance Analysis (BIA) assesses body composition based on the impedance of low-frequency electrical currents sent through extracellular fluids and high-frequency currents through intracellular fluids for a more accurate, complete measure.
