Risk of using treadmills

One of the most popular and widely advertised methods of exercising remains using treadmills. Most gyms and fitness centres will show members exercising on a treadmill to lose weight and become fit.
However in addition to being expensive, there are some risks involved in purchasing and using a treadmill which few are aware of.
A treadmill is a mechanical device, and there is always a possibility of a mechanical failure because a component will fail due to poor quality, design or lack of maintenance.
This can be dangerous for the user of the treadmill and in some cases fatal.
The death of the CEO of SurveyMonkey David Goldberg is one instance, where a person met with a fatal accident while exercising on a treadmill. He was exercising alone when he met with an accident and the delay in getting medical attention proved to be fatal.
