Too Much Exercise Is Gross, Dangerous

Madonna’s sinewy arms, Elle Macpherson’s “saggy knees,” Nicolas Sarkozy's collapse: Extreme exercise regimes are taking a noticeable toll on some celebrity bodies, highlighting the negative effects of an overly heavy workout, the Times of London reports. Experts say too much exercise does nothing to make us look better—instead, a 3-hour-a-day workout can take a toll on health.

Some celebs “work out to the point at which their body-fat levels become so low, there are signs of muscle wastage and fatigue,” notes a personal trainer. An exercise expert says if you’re not a pro athlete, you shouldn’t be burning more than 3,000 calories weekly, which translates to “walking, running, or cycling more than three miles a day,” the Times notes.
