How to Train A Dragon? No. How to Train Your DNA.

 "Tired of your look? Want to change your body? Get off your lazy butt and EXERCISE!" Everyone has been called lazy at least once in their lifetime and who can we blame? Life does get tiring sometimes, but for those athletes, fitness freaks and jocks, working out is an everyday goes-without-saying activity. They aspire to change their body for the better. Little do they know that as they work to change their body, they are actually changing their DNA methylation for the better as well.
DNA methylation is when certain expressions of the gene are turned 'on' or 'off' in accordance to improving the organisms bodily functions. It has bee hypothesized  that exercise changed your genetic code entirely, but this hypothesis was ruled out by scientists such as Professor Juleen Zierath. Zierath proved that the alteration in DNA methylation caused by exercise led to better protection of cells from oxidative damage along with improved transport of fats, sugars and other nutrients throughout the body. Her study involved observing the muscle tissues of a group of people that just carried out a 20 minute workout session and comparing their muscle tissues to a group of people who did not participate in the workout. She also compared the workout group's skeletal muscles 3hours before and after the workout to further identify the alterations. It became evident from this comparison that he alterations made in DNA methylation were to improve and make better the body's performance.
It was also stated by another researcher who contributed to Zierath's study, Dr. Donal O'Gorman, that regular exercise and workout activities were essential for metabolic health and prevention of diseases. Regular exercises are needed because the alterations in methylation are not permanent, they are, in simplest terms, our body's response to exercise. To get this response, we must workout regularly and even daily, as though to 'remind' our DNA to turn certain expressions 'off' while leaving others 'on'. By exercising, it is as though we teach our DNA to transport nutrients more efficiently, build muscle, and improve our bodily functions to be healthy.
