You need to move somehow and get that sweat out of your body. Your body needs to at least have some activity for it to shed some pounds and remove the toxins in our body. That's why if you're thinking of doing something else, have some physical activities and start the initiative of it. It's hard at first but you have to do it if you love yourself. It's much worse if you'll not take any actions and you'll just have to pay a visit in the hospital, you don't want to do that and so do it while it's still early. Even if you're mentally fine, your thinking will change if your not mostly doing any activity whole day.
Yes, it is true that physical activity needs to be done to maintain fitness which is of course for health, because with a healthy body, all activities carried out will be much better, I think health is number one to prioritize, because in doing physical activities, mental health will also be carried away, there must be a solution to think about in living a better life.
Everyone will take care of themselves once they feel fatigued or when they are admitted to the hospital. That is why those that have experienced those health issues and even if they are not very active in it. They're starting to live a healthy lifestyle because they don't want it to happen again. And as prescribed by doctors, it will all go down from there and they'd tell us to take care our health, make some movements, do some exercises. Although I am not a doctor to tell it to the internet to do this or that, but based on experience, that what worked for me.
