Lack of desire and dread when it comes to physical activity is not always due to laziness. The reason for this reaction lies in the genes, researchers say.

For most people, exercise releases endorphins, which increase mood and euphoria and stimulate the body to perform more physical activities. For others, however, shortness of breath, sweating, and exertion can cause a different response in the brain to have the opposite effect.

In their study, the researchers found that willingness and tolerance to exercise can be up to 50% genetic.

Participants are assigned a fitness program. After a while, half of the volunteers continued to exercise willingly, while the other half gave up much sooner.

Scientists explain that some people are genetically predisposed to lower physical capacity, and sometimes even just cooking and cleaning the house can be enough to tire them out.

When the threshold of tolerance and comfort is reached when performing physical activities, we choose to stop the activity, and there is nothing shameful in that, experts explain. An exercise is useful when it is desired.

In the case of genetically determined low physical capacity, the application of lighter physical activities, such as swimming, light running, dancing, is recommended.
