Knowing how to use the Samsung Galaxy Watch 4 to measure body composition means you can start to enjoy the outstanding health feature of your smartwatch.
Bioelectrical Impedance Analysis (BIA), a technology found on the best smart scales, uses a small electric current to determine body composition. Body composition data collected from Samsung Galaxy Watch 4 includes body fat percentage, body mass index (BMI), muscle mass, bone mass, body water percentage and more.
Taking a BIA reading on the Samsung Galaxy Watch 4 is quick and easy, especially compared to the effort it would take to get your physical makeup tested in a doctor’s office. That said, you will get a better understanding of your health by consulting a professional, so don’t use the Galaxy Watch 4’s body composition feature as a substitute for regular checkups.
There are a few other things you should know before using the body composition feature, including whether it’s right for you in the first place. Here’s what you need to know beforehand and how to use the Samsung Galaxy Watch 4 to measure body composition safely and get accurate results.
Samsung Galaxy Watch 4 body composition: is it safe? Is it correct ?
In general, people with a pacemaker or pregnant women are not recommended to use the BIA. Research suggests that people with pacemakers shouldn’t experience any side effects after using BIA, but you should see your electrophysiologist or cardiologist first.
Experts also say BIA is safe during pregnancy, but again, ask your doctor for advice. Also consider using the body composition feature under professional supervision. Many smart scales have a “pregnancy mode” that turns off BIA, but the Galaxy Watch 4 does not, so take precautions.
Additionally, Samsung says measurements might not be accurate for those under 20, but doesn’t appear to place any real age restriction on the feature.
In terms of accuracy for everyone else, we and our fellow reviewers saw varying degrees of similarity between our Galaxy Watch 4 and smart scale body composition readings. If your goal is to track changes in your body composition, it is advisable to take measurements at the same time each day (preferably in the morning). You’ll also want to follow the steps below on how to use the Samsung Galaxy Watch 4 to measure body composition for the best results.
How to use the Samsung Galaxy Watch 4 to measure body composition
1. Step onto a scale. Before using the Galaxy Watch 4’s body composition feature, you need to know your weight. We used the affordable Wyze scale in our tests, but any scale – dumb or smart – will do.
2. Open the body composition app on your Galaxy Watch 4. It should come pre-installed in your tiles.
3. Enter your weight. Giving your Galaxy Watch 4 an accurate weight may give more accurate results. But again, think about consistency. Plan to take body composition measurements at the same time as you step on a scale, for example, first thing in the morning.
4. Move your watch higher on your wrist. You want it to rest more on your forearm than your wrist bones.
5. Place your middle and ring fingers against the set of crown keys with the palm facing up. Do not press either of the two buttons, otherwise you may accidentally quit the body composition application.
6. Lift the back of your unconnected hand so that it is not resting on your other hand. You don’t want your hands to touch.
7. Lift both arms away from your body. You don’t want your arms to touch your torso. Yes, we know the position is tricky, but you are almost ready.
8. Press start and return to your position.
9. Wait 15 seconds for the body composition reading from Galaxy Watch 4.
You should now see a summary of your body composition reading. You can view the metrics on your wrist or access the Samsung Health app on your smartphone for further analysis.
