Biologists at the University of California, Riverside have found that voluntary activity, such as daily exercise, is a highly heritable trait that can be passed down genetically to successive generations.
Working on mice in the lab, they found that activity level can be enhanced with "selective breeding"- the process of breeding plants and animals for particular genetic traits. Their experiments showed that mice that were bred to be high runners produced high-running offspring, indicating that the offspring had inherited the trait for activity.
