Your bathroom scalesOne number for your whole body, usually from your feet alone.
Our TanitaEight electrodes and multiple frequencies — measuring each arm, each leg and your trunk separately.
What it measures
Muscle mass — each limbLeft vs right arm and leg, plus trunk. Spots imbalances after injury or from favouring one side.
Fat mass & body fat %Overall, and where it sits in your body.
Visceral fatThe fat stored deep around your organs — the type most linked to health risk.
Body waterTotal water, and the balance inside and outside your cells — linked to hydration, inflammation and recovery.
Phase angleA marker of how healthy your cells are and the quality of your muscle tissue.
Bone mass, BMR & metabolic ageEstimated bone mineral, the calories you burn at rest, and how your metabolism compares with your age.
Why it matters
Two people can weigh exactly the same and be in very different health. Muscle naturally declines from around the age of 30 — a process called sarcopenia — and it protects your metabolism, your joints and your independence later in life. Tracking it, limb by limb, lets us target the right changes, such as strength training and protein intake. For athletes, segmental lean mass and phase angle help track how you are adapting to and recovering from training.
Before your test: avoid a large meal or lots of fluid for 2–3 hours. Not suitable if you have a pacemaker or other implanted electronic device, or are pregnant.
