How do I measure skinfolds?

You can measure your skinfolds using a caliper, a device utilized to measure an amount of skin. If you were to pinch your skin at certain places (e.g., tricep, bicep) and measure the fold, you would be measuring subcutaneous fat stored below your skin.

Skinfold test and body fat

There are three types of body fat:

  1. Subcutaneous fat, stored right below our skin;
  2. Intramuscular fat, located inside the muscle; and
  3. Internal fat, which is around our internal organs and serves as a protective shield.

This type of skinfold test is a reasonably accurate body fat calculation technique and can help you observe changes in your body fat percentage over time.
