Endurance running may not only be just great for your heart, but your sex life as well. According to a new study published in the journal PLOS ONE, there is a link between testosterone levels of both men and women, their hands and the speed at which they run.

Now I’m sure this all sounds very strange, but there is in fact some scientific evidence behind all of this. After testing a large pool of  marathon runners and scanning of their hands, the study – conducted by researchers at the University of Cambridge’s Division of Biological Anthropology – concluded that people with ring fingers that are the same length or longer than their index finger have higher testosterone exposure, which equates to a higher sex drive in women and healthier sperm count in men.

The females of the test group that had longer ring fingers (and therefore high testosterone levels) completed the race about 12 minutes faster than those with shorter finger. The males of the group with longer ring fingers ran almost 25 minutes faster.
