Interesting new Finnish study comparing identical twins where one twin exercised, the other was sedentary.

This supplemental blog post by physiologist Michael J. Joyner MD has a stunning photo example where one identical twin was a weightlifter, the other an endurance runner.

It turned out that these genetically identical twins looked surprisingly different beneath the skin and skull. The sedentary twins had lower endurance capacities, higher body fat percentages, and signs of insulin resistance, signaling the onset of metabolic problems. (Interestingly, the twins tended to have very similar diets, whatever their workout routines, so food choices were unlikely to have contributed to health differences.)
The twins’ brains also were unalike. The active twins had significantly more grey matter than the sedentary twins, especially in areas of the brain involved in motor control and coordination.
