Commercial treadmills are designed for heavy usage and are more reliable and durable than the less expensive models, which is why they are used by health clubs and recreation centers. Commercial treadmills are better built than the non-commercial models, the components and materials are of a higher quality and they are designed to withstand frequent or continuous usage. Your Birmingham, Montgomery, Fayette, or Mobile Alabama health club or fitness center will be easily served by Atlanta-based Fitness Equipment Sales.
