The more exercise we do, the lesser the risk of us dying from heart disease but that is true to a certain point. Remember that saying that too much of everything is bad? It also applies to exercise too.
According to researchers that examined how much exercise is too much, running more than six kilometres a day could be dangerous to your health.
Among walkers, the turning point, when benefits were lost, was seen in those who did more than 74 kilometres per week, or 10 kilometres per day.
The study was led by Paul Williams of the Lawrence Berkeley National Laboratory and Paul Thompson of the Department of Cardiology at Hartford Hospital.
Experts generally recommend two and a half hours of moderate exercise each week, or 75 minutes weekly of vigorous exercise for a healthy heart and body.
So how much exercise do you do every day?
