Ax/s

Introducing Ax/s

Know your body. Completely.

The Ax/s is our most advanced body analysis scale — rebuilt from the ground up with multi-frequency BIA technology and eight high-precision sensors to deliver a complete, clinical-grade picture of your body composition.

Where other scales measure weight, the Ax/s measures you: fat, muscle, water, bone, metabolic rate, and more, mapped across your entire body and synced seamlessly to your phone. Precise, intelligent, and designed to disappear into your daily routine. This is the pinnacle of body comprehension.

Understand your health data with our Health Concierge

Male, 56 — Sedentary Professional
Weight has crept up over the years.
Visceral fat and metabolic rate are the real story.
Highlighted metrics:
Visceral fat
Rating 13
Slightly elevated, High range
Body age
64
8 years above chronological age
Basal metabolic rate
1,580 kcal
Low for height and weight
Robert, your visceral fat is currently in the high range — this is the fat surrounding your organs, and it carries more health risk than the number on the scale suggests. Your basal metabolic rate is also lower than expected, meaning your body is burning less energy at rest than it should be. The priority here is not aggressive dieting but building movement into your day: even an additional 20 minutes of walking daily can begin to shift both markers over the next four to six weeks.
Male, 33 — Active but Unaware
Exercises regularly but body composition tells a different picture. High body fat despite a normal weight.
Highlighted metrics:
Body fat percentage
28%
Higher than expected for activity level
Skeletal muscle rate
36%
Below optimal range
Body balance
31% delta
Asymmetry detected (upper vs lower)
Marcus, your weight sits in a normal range but your body fat percentage suggests your composition is not reflecting the effort you're putting in at the gym. Your skeletal muscle rate is lower than expected, which may mean your training is not translating into the muscle growth you're after — nutrition and recovery are likely the missing piece. Your body balance also shows an imbalance between upper and lower body, which is worth addressing to protect your joints and improve overall performance.
Female, 25 — Body Recomposition
Tracking progress through training. The scale proves her results even when the number barely moves.
Highlighted metrics:
Muscle mass
36%
Up 1.8 lbs over 6 weeks
Body fat percentage
23%
Down 2.4% in a month
Body water
57%
Well within optimal range
Danielle, your weight has barely shifted but your body is telling a much better story — muscle mass is up and body fat percentage is trending downward, which is body recomposition working exactly as it should. Your hydration levels are consistently healthy, which is supporting both your performance and your recovery. Keep your current routine and protein intake consistent; the data shows you are moving in exactly the right direction.
Female, 48 — High-Functioning Burnout
Looks fine on the outside. Low muscle mass, elevated body age, and early warning signs her body is running on empty.
Highlighted metrics:
Body age
52
4 years above chronological age
Muscle mass
44lbs
Low for height and frame
Body water
49%
Below healthy range
Lauren, your weight looks normal but your body age is reading older than it should, which is often a signal that chronic stress and under-recovery are taking a toll beneath the surface. Your muscle mass is lower than ideal for your frame, suggesting your body may be breaking down muscle rather than preserving it — a common response to prolonged stress and insufficient rest. Prioritizing sleep, increasing protein, and adding even light resistance training twice a week could meaningfully shift all three of these markers over the coming months.
