I went to the gym recently and found many people walking on the treadmill. I'm confused. Shouldn't they be running on the treadmill?
Honey! Running is the climax in the middle, and it is used to warm up and cool down quickly before and after. If you walk from beginning to end, it may be a random activity, right? It is possible that he can't run because his knee joint is not good, so he chooses to go quickly ~ ~ I don't know anything else, I hope I can help you ~
