Walking for 30 minutes every day has the same effect as jogging, playing tennis and riding a bike. In addition, it has a good effect on preventing diabetes, heart disease, osteoporosis and some cancers. The report pointed out that the so-called fast walking means walking 1 mile (about 1600 meters) in 12 minutes. If you walk for 45 minutes to 1 hour every day, the probability of stroke can be further reduced by 40%. People who have no exercise habits can achieve good results as long as they walk for 30 minutes every day from now on.
