It is ok to keep healthy and lose weight by running ... Running is to control the rhythm, fast walking, jogging, moderate speed, acceleration and deceleration ... In short, you can't run at a uniform speed, otherwise it will be difficult to achieve the effect of exercise. Generally, the speed of one cycle is changed in 20 minutes, 1 ~ 2 cycles. The following is the key, you can't stop immediately after running, you must do all kinds of stretching exercises. Leg press, stretching Achilles tendon, chest expansion, etc. In short, I did all the stretching exercises that I could do. If you don't stretch, you will basically run away in vain. If you have a big belly, you can find a mat and do abdominal exercises after stretching. You can find a video online. If conditions permit, it is best to go to the gym to do spinning, which is the fastest way to lose fat! Above ~
