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 your body is basically a machine. Let it sit “idle”, and it falls into disrepair. Keep it tuned up, and you will see it operating well for decades.

There are ample studies that show the best way to lose excess weight, permanently, is to walk for an hour, 3-4 days a week. Do that, and pounds will melt away gradually, you will not “plateau” as with other exercise programs, and you will KEEP those lost pounds away. Even if you change NOTHING else about your habits.
