Doing physical exercise, I heard that doing physical exercise, such as getting on the bus and lifting heavy objects, is good for human exercise, is there any harm, and can it replace bodybuilding training. There is no substitute. But there is no harm in manual labor. Manual labor can only exercise a limited part of your area.

Fitness is a purposeful comprehensive exercise. It can make your whole body get exercise.

While manual labor is not. For example, if you lift a heavy object, it can only exercise the strength of your arm. But you worked out. Is to exercise the whole body.
