I think this is a small thing in life. Many of these little things will become big things when they are put online. It is really wrong for an insignificant thing to cause such a comment. If you want to ask me if running like this will affect others, I don't think it will affect at all. Everyone is free to move. His behavior is unrestricted and free on the premise of not violating morality and law.
We have no reason to stand on the moral high ground and accuse others of their freedom. You are asking others not to be free for your own freedom. This is an immoral thing. I'm on my uncle's side. There's nothing wrong with insisting on exercise. As a man, I think this is a normal thing. Even if I am not an old man, many young men may go shirtless when tied up, or we will go shirtless when it is hot. Why does this routine cause so many wars of words? I was thinking, too.
To sum up, I don't think it is an uncomfortable behavior for everyone to run in the park with bare arms. On the contrary, I should advise those who spray everything to restrain themselves. Have you ever been shirtless?
