The Body Expert system has the highest prediction accuracy (over 90%) because

All algorithms are developed by scientific experts

The system uses not one but six calculation algorithms

It is based on formulas created by Casey Butt, MD during 6 years of research.

To improve accuracy, the system also analyzes muscle length (classic test).

It takes into account the presence of diseases, body fat percentage and real progress.

Nota Bene! Many people do not trust the accuracy of such algorithms, citing the example of some professional athletes, whose data do not correspond to the results. However, do not forget that almost all athletes in professional bodybuilding take anabolic drugs, which allows them to achieve such results.

Ankle circumference

Ankle

Ankle circumference is measured with a centimeter tape at its narrowest point. If you don't have a centimeter tape, you can use any string or thread. Wrap the string around your ankle, fix the length and measure it with a ruler.

Wrist circumference

wrist

The circumference of the wrist is measured in the same way as the circumference of the ankle, as described in the paragraph above.

You need to perform the test as described in the article in the bench press and biceps curl.

Determining biceps length

The figure shows the distance from the beginning of the biceps to the forearm. The measurement is taken with a ruler.

Biceps

Bend your arm at the elbow at a 90-degree angle.

Place the ruler at the elbow so that it rests on the forearm.

Tense your biceps.

Feel with your finger the transition of the biceps ligament into the muscle itself (you can feel it even in poorly trained people).
