out of anthropology known, the man has been in a hunter role. it is not a secret the more you exercise the better is your feeling. but not to all human types. there are a few different human types that has determined metabolism. those who has fast metabolism can gain or lose gain fast. those who has slow metabolism they should exercise continuously.

the most man out of history and anthropology run around 60 miles per day. the women are the one who are carrying the baby and collecting the goods. this means they were moving also, but far less than men.

by type of your body you cannot say that excessive exercise is unhealthy. someone with slow metabolism will have enough in half an hour, but someone with fast metabolism will not have enough like never..
