A recent study published in the journal PLOS Genetics found that exercise isn't just good for your overall health, but can also have an impact on how certain genes are expressed.

During the study, researchers observed 23 slightly overweight men over the age of 35 taking part in a spinning class twice a week. After six months, they found that exercise had actually helped changed the way these mens' bodies stored and burned fat.

And that's not the only upside of exercise. Below are a couple more reasons to get moving according to science:

Exercise can be a learning aid: People who exercise immediately after learning a new skill are more likely to retain that information than those who exercised before learning the skill, or not at all, according to a 2012 study published in the journal PLOS One.

It may help you live longer: Working out for just 15 minutes a day might add as much as three years to your life, according to findings published in 2011 in the journal Lancet.

You'll look and feel better: Once you start making a commitment to exercise, your body will eventually start to shed fat and gain muscle. This can have a positive impact on your confidence and mood.
