There are two main sources to go to for a good treadmill consumer guide - a library and the internet.
I ran quickly search the Internet to treadmill consumer guide, and soon the results of thirteen was considered high quality. A web site dedicated to providing a very valuable guide is also online.
One called Advanced Fitness is run by a manufacturer of treadmills, but also provides a forum for consumer reports. Although perhaps not the most objective site, it is a very useful tool for the general public know what is said about the specific model.
Public health magazine Prevention,
Runner's World magazine offers a good guide can also be reviewed in the library Epinions and other sites is the price, rating, and review of the legal model treadmill.
Finally, each consumer reporting publication or public website must have a treadmill and workout guides instructions at all the equipment in general. This industry is big business, with hundreds of millions spent on each year. Make sure that this guide, and it offers the assessment, is valid.
