A woman's back and a man's beer belly

December 16, 2007 04:32 PM

It is not surprising that evolution designed women to carry the load of a pregnancy in front without forcing the contraction of back muscles with the attendant shear loading. Check this out.

Men, on the other hand have not yet evolved an adaptation for beer belly. The weight out front is countered by a contraction of the erector muscles in the back. Back ache and eventually shear stress are the consequence.

Art,
I've been meaning to ask for some time, and this seems as good a place as any. I recall somewhere in your posts that men need to maintain a 13% BF (or less) to maintain healthful hormonal balance.
What would the appropriate body fat % be for women?
Thanks.
