The UK is the third laziest country in Europe, according to a paper. The research shows that 63% of people in the UK do not take enough exercise. A report last year said that inactivity is the fourth leading risk reason for dying too early.
Being active helps you keep away from illness. So instead of watching the Olympics on the television, shouldn’t we be going for a run Why not play badminton or tennis rather than sit on the sofa without moving for a long time Exercise for a short period of time may not have a large influence on your body. However, if you keep up exercising, it must bring you both pleasure and health.
The amount（数量）of activity required to be healthy is important. As an adult, you need to do a total of two-and-a-half hours’ exercise a week. Luckily, the research shows that doing 10-minute activity every day also works. You are more likely to stay healthy if it is part of your everyday life, for example walking or riding a bike to work.
It is not just adults who need to take exercise. As soon as your children can walk, they should also be encouraged to run and jump. The research shows the kids under five years old spend so much time in cars that they are at risk of being unhealthy or overweight before school age. Between the ages of 5 and 18, the research suggests an hour of exercise a day is needed. Exercise at this age helps develop strong bones（骨）and muscles（肌肉）and reduces the risk of being overweight. Also, the old are advised to do two-and-a-half hours of activity a week. This can reduce（降低）the risk of falling over.
So don’t be lazy and make sure you are an example to the people around you, go outdoors and do some sports together with your partners.
