Proportionality of body — McCallum's formula

This formula was created by expert methodist John McCallum. It's based on the wrist girth:

  1. 6.5 waist girthis a chest girth.
  2. Waist girth equals 70% of chest.
  3. 53% of the chest equal to hip girth.
  4. Neck is equal to 37% of chest girth.
  5. Biceps is equal to 36% of chest girth.
  6. Lower leg is equal to 34%.
  7. Forearm girth is equal to 29% of chest girth.

This formula isn't correct for everyone because it suggests that the size of the wrist strongly depends on the size of other human bones.
