Gym is an organized platform for doing fitness training. But there is no such thing that it’s mandatory to go to the gym for keeping yourself physically fit.
You can simply see so many people around you that doesn’t go to the gym yet are physically fit.
It’s just a misconception that you need to go to a gym to get yourself physically fit. I am not against the benefits of going to the gym but I am also against the fact that it is something mandatory.
