| Walking is the best and the cheapest way to lose weight. The best time to walk to lose weight is in the early morning in fresh air, because it has many benefits. Firstly, it doesn't disturb your daily routine activities.Secondly, it does not only help lose weight, but it's also useful for good health. Thirdly, you won't get an excuse that you didn't get time to go for your workout due to your tight schedule. It's scientifically proved that walking in the early morning to lose weight helps you to burn calories faster than at any time of the day.Having a good morning walk and then a healthy breakfast can help to increase the metabolism (新陈代谢) of your body. As the metabolism increases, you burn more calories. The first thing to do is to set up a goal that you want to achieve. Therefore, work out a walking routine. At first, start walking three times a week, and then slowly increase it to five times a week. It's advisable not to overdo walking, as it can have side effects on the body. Here are certain easy steps that you need to follow when you start your daily walking routine. Warm-up is an important activity that is to be done before you start to do any kind of exercise. A light warmup period of about 15 minutes is enough. It will warm up your muscles and avoid any injury to your body. Exercising without warmup can be dangerous and must be avoided. Make sure that you don't stop anywhere in between your 30 or 45 minutes' walk. Slow down if necessary. Stopping in your walk won't help you. Instead, slowing down your speed will help to burn more calories. While walking, take long strides (步伐) and swing your arms in a rhythm.This will use up muscles and help burn more calories. In a word, regularity and correctness in walking is the key to success. Best of luck！ | ||||||||||||||
