Of course, it is best to rub it before running and after running, but if you choose one, I personally think it should be rubbed before running, and it can be wrapped with plastic wrap or something, so that the skin will get hot and the pores will open during exercise, which can promote the absorption of essential oil [some slimming products are also recommended to cooperate with exercise after use]. In addition, according to personal experience, if you want to wrap plastic wrap, you should also pay attention to inserting a few small holes evenly on your legs after the whole package, which is easier to sweat than wrapping it tightly.
Pay attention to stretching and massage after running.
