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.

The reasoning that exercise specialists give is that you’re not getting more fit WHILE you exercise. The exercise (the load on your muscles, the increased depletion of energy stores, etc) just changes the mode your body is operating in. Getting these signals, it starts rebuilding itself in a different way, for example, growing muscle.
If you think about it, it’s pretty improbable that your muscles only grow during the time they’re stressed. It’s more of a recovery/adaptation activity.
