Why is my navy number higher than the scale?

Different lies. Trust the trend and the photos.

Can I use it while I have a lot of belly fat?

Yes. It was built for that kind of waist.

Should I suck in for the tape?

No. Relaxed. The same tension every time. Sucking in is a different measurement.

Can I navy-tape after a workout?

Wait. Sweat and a pump change the waist. Use a quiet morning.

Guides/Navy body fat method

Navy body fat method

The navy method is a tape formula. It is not a lab. It is good enough to see if you are moving, and cheap enough that you will actually do it twice.

How to tape

Waist at the navel, relaxed, not sucked in. Neck just below the larynx. Women add hips at the widest point. Same time of day, same tension on the tape. Plug the numbers into the calculator.

Do not marry the decimal

It can be a few points off DEXA. Fine. If navy says 18 and then 15 with the same tape routine, you got leaner. That is the point. Then follow a blueprint instead of hunting a more expensive guess.

Tape on a schedule

Same day of the week, same time, same spot, not sucked in. Write the number next to the waist. That is a navy method practice, not a science fair. If you tape angry after a salty dinner, you will get a story, not a trend.

Use the calculator on this site, then go lift and eat. Another decimal will not reveal abs. A deficit will.

Same tape, same hour, same story

Navel, relaxed, not sucked in. Neck just under the larynx. Women add hips at the widest point. Same weekday, same tension. Write the number next to the waist. Angry taping after a salty dinner is a story, not a trend.

The formula is not a lab. If navy says 18 then 15 with the same routine, you got leaner. That is the job. Then follow a week, not a more expensive guess.

It can disagree with the scale and still be useful

Different lies. Trust the trend and the photo. You can use navy with a large waist. It was built for that. Do not marry the decimal.

Open the body-fat calculator on this site, then go lift and eat. Another tenth of a percent will not reveal abs. A deficit will.

Pick this method and stop shopping gadgets

Switching DEXA, calipers, and a cheap scale every month is how you stay confused. Marry the tape plus a photo. Measurement is a compass. It is not the walk.

Monthly is plenty. Weekly waist is more useful day to day than a new device.
