why does only 30-60 minutes of exercise make big changes to your body and heath?

I have heard of and even seen peope make big changes to their body and health with only 15, 30, or 60 minutes of exercise a day. It doesn’t even seem like much.

Whether it’s cardio or lifting weights, why do people only need that much time a day to improve? In fact, why does MORE time with exercise (like 3 hours or more) even seem harmful?

I know diet plays a big role but still. Like I started strength training for only 15 minutes a day and I see some changes in my body physically.

Because are bodies evolved to be a little active. Not completely sedentary, not constantly active. Every animal is different. Cats sleep like 20 hours a day. For us, 60 minutes of moderate activity is about right.
