how do you define a physically fit person?

when you can able to endure stong physical activity for a long period.

A person who has no mentle or physial illness. A person who is not physically or mentally handicapped. A person who is not a ill hearted & ill behaved. A person who is never lazy & intrested to work. A person with knowledge, brain, efficiency, effective, social and determind to succede is called a physically fit. I think.

The muscles have to be good toned and at least a bit evolved. The person can't be overweight or underweight for that matter. Skin color should be vivid (according to the person's nationality) and he/she shouldn't have any physical problems like back pain, wrist pains, etc. A physically fit person practices sport and is therefor much healthier than the average individual.

We can tell to a person if he is fit or not. We already tell is lively and on the go always. Someone told me that if your sweat more thats one of the sign also that that person is healthy.
