How to measure consistently
Progress tracking only works if each measurement is taken the same way every time. Measure in the morning before eating or drinking, with a relaxed (not flexed) muscle, using a flexible tape held snug against the skin and parallel to the floor. Measure the chest across the nipple line, the waist at the narrowest point (usually just above the navel), the hips at the widest point around the buttocks, and limbs at their thickest point. Because left and right sides differ slightly, this tracker records biceps and thighs separately. Nothing you enter leaves your device — the data is saved only in your browser.
Why track measurements instead of just weight
The scale can stall or rise even while your body composition improves, because muscle is denser than fat and water weight fluctuates day to day. Tracking girths — waist, hips, chest, arms and legs — alongside weight shows the shape changes the scale hides, which is why the chart above lets you follow any single measurement over time and compare it against a goal. For a composition estimate, pair this with the Body Fat Calculator.
