Welcome
Neither LifeSpan Fitness nor its representatives can accept responsibility for any damages or
injury incurred as a result of information presented in this manual except under the terms
of the product warranty.
Congratulations on choosing the LifeSpan Workplace™ line of products. These
products give you the opportunity to remain productive while taking care of
yourself as you integrate movement with normally sedentary tasks.
The average American now spends eleven hours, ve days a week, sitting, and
burns one-hundred fewer calories each day than they did a few decades ago.
Sitting for long periods slows your metabolism, reduces calories burned, and
increases your risk for heart disease and diabetes.
Whether you plan on placing this product in a TV room, replace your desk at
home or are adding another workspace in the oce, LifeSpan Workplace™
products are a great way to add movement to an otherwise sedentary activity.
Before you assemble or operate your product, please read this manual
thoroughly. Important information, including safety precautions, ongoing
product maintenance, assembly instructions, and information on proper
operation are included.
If you need to contact LifeSpan customer service, visit our website at
www.LifeSpanFitness.com and select customer service. Complete the
information requested and we will respond to your inquiry within one
business day. In the United States and Canada you can also call
[phone] and choose option 4.
