Who gets it right: Sharon Stone, 54
One of the most common mistakes I see people making is over-exercising. Working out too hard or too much will lead to a sidelining injury. The key is – as it is with almost everything – moderation. Stay active all day instead of trying to get your physical activity in for the day in an hour at the gym.
