Exercise does have some immediate health benefits.
It improves the flow of blood to the brain - improving concentration and helps us maintain a healthy weight range. Most of all exercise is fun and is a great way for us to meet new friends. To help improve our health we must do 30 minutes of exercise on most, preferably every day of the week. This exercise does not have to be vigorous, it can be moderate including things like walking or swimming. Exercise - you only have to take it regularly not seriously.
