　　What Happens When You Stop Exercising

　　Have you ever wondered what would happen if you stopped exercising? A new study on twins was published in the journal Medicine & Science. The results of the study are dramatic.

　　In the study, researchers looked at 10 pairs of twin men. Each set of twins was in their mid-30s. Each had been brought up in the same family. Since they were identical, they shared the same DNA. They had maintained the same level of physical activity for most of their lives.

　　But there was one difference. One twin of each set had cut on exercising in the past few years due to work or family pressure. On average, the less active twin exercised less than twice a week, while the active twin exercised at least twice a week. The research team put each twin through a set of medical tests to study their overall health.

　　The results showed big differences. While the more active twins had lower body fat percentage, better endurance level, and normal sensitivity, the inactive twins had about seven more pounds of body fat, worse endurance, and signs of disease. Not only were their bodies different; their brains were different as well. The active twins had more gray matter (the information processing part of the brain), particularly in areas that control balance.

　　The conclusion of the study is clear. Quitting your fitness routine can bring negative effects to your body and your brain as well. Considering the less active twins in the study had become couch potatoes(沉溺于看電視的人)only recently, these changes can sneak up on you a lot sooner than you'd think. So keep exercising. It is beneficial to your overall health!
