The speed of running can be calculated by a simple formula, speed = pace frequency x stride. For beginners, it is difficult to master the method of increasing step frequency and stride length. You can simply swing your arms quickly to drive your legs when running. You can swing your arms faster and your feet will have a faster rhythm.
Put your hands in this position (at the top of your hip). Then imagine the line pulling forward and the legs stepping out alternately. At this time, the muscles of the buttocks and the inner thighs are used, and the waist is naturally pushed forward, and the buttocks are actively sent. When running, your hands bend slightly to keep a certain rhythm, and your elbows drive your arms to swing back and forth naturally.
Of course, running to lose weight can increase energy consumption and lose weight, but there are also cases where the weight does not drop but increases after running exercise. Why is this?
First, there is a large amount of exercise and a large appetite. Some people just started to lose weight by running, and then they lost weight again after a period of persistence. This is because running can stimulate digestive organs and increase appetite while consuming energy substances. At first I was able to control my diet and lose weight. After a while, because of the unbearable hunger and the novelty of losing weight, I simply overeated and gained weight.
Second, we can't persevere. Some people stop exercising after running for a while because they lose interest. We should know that the digestive system changes more slowly than the exercise system, and the energy consumption is obviously reduced after stopping exercise, but the absorption function of the gastrointestinal tract remains "vigorous". Of course, if you weigh it, you will gain weight.
