Treadmill Desk Overview:

2013 Model - The TR800-DT3 is a walking treadmill and console that works perfect with the S2S height adjustable standing desks. The compact console sits on your desktop and gives you easy access to the control buttons and workout readouts without getting in the way of your work. The LED digital display shows steps taken, walking time, calories burned, distance travelled and walking belt speed. In addition, this new console is Bluetooth-enabled so you can connect wirelessly to your Windows or OS X computer to automatically track results while you exercise. Once you’re done walking, sync your data with your LifeSpan Fitness Club account to retain your exercise history online. The console also comes with one USB port for charging portable devices.

The TR800-DT3 whisper-soft treadmill has a 2 HP DC drive motor for up to three hours of daily use, ideal for single users. Speeds range from 0.4 to 4.0 MPH for optimal speed for walking while you work. The small foot print of this treadmill has an 18” by 52” walking surface that is equipped with six compression shocks and can support users up to 300 lbs. The treadmill fits under most standing desks with posts at least 29.5 inches apart at the base. The treadmill has a step up height of 4.25" from floor to the top of the walking surface.

The TR800-DT3 is backed with a lifetime warranty on the frame and a three year warranty on the motor.

Well Designed Console:

LifeSpan TR800-DT3 Console

 The small contemporary design console is 12.9” long by 2” tall by 3.25” wide and sits on your desktop and is small enough to not get in the way of your work. The digital LED display shows steps taken, walking time, calories burned, distance traveled and walking belt speed. The weighted console has a safety key that shuts down the treadmill when removed.


LifeSpan TR800-DT Bluetooth

 The TR800-DT3 is Bluetooth-enabled to wirelessly sync your data to your computer and share with a specially designed app that sits on your computer desktop. Track your steps taken, walking time, calories burned distance traveled all on your computer screen as you walk. Once complete, sync your data with your online LifeSpan Fitness Club account to retain your walking history.

 USB Charging Port:

LifeSpan TR800-DT3 USB Charging Port

 The TR800-DT3 comes with one rear USB port for charging portable devices. Charge your iPod, cell phone or other USB device right on your desktop.

 Intelli-Guard and Intelli-Step:


 The TR800-DT3 comes standard with two of LifeSpan trademarked technologies: The built-in Intelli-Guard™ automatically stops the belt if you step off during your walk for added safety and is a major development in protecting treadmill users and those around them. With the Intelli-Guard™, you no longer have to worry about leaving your treadmill running if you have to step off to take a call. When your foot no longer continuously strikes the belt surface for 20 seconds, your treadmill will automatically pause.  Intelli-Step™ counts and records the number of steps you take and displays them on the console. More accurate than a pedometer, Intelli-Step automatically detects the impact of your foot striking the treadmill belt.

What type of work can be done on the Treadmill Desk?

Most of your daily tasks that you would normally do at a conventional desk can be done while using the treadmill desk. Talking on the phone is also an easy task and with a bit of practice, hand-writing feels quite natural as well. You can also touch the Pause button on the treadmill desk at any time to write notes or other tasks requiring less movement and your treadmill desk becomes a stand-up desk. When you are ready to continue walking, touch the Start button again and your treadmill desk picks up right where you left off without losing any of your data.  

 Is the treadmill desk quiet?

Yes. We designed the treadmill desk to be used in an office with co-workers nearby. It only makes sense that you could carry on a conversation with the sound of a machine getting in the way. The decibel level depends on the speed: 1 mph is 47 dB, 2 mph is 50.1 dB, 3 mph is 54.2 dB and 4 mph is 59.8 dB. To give an example, at 2 mph the treadmill desk makes less noise than a refrigerator and at 4 mph it is still quieter than an air conditioner.

 Does the treadmill desk have an incline feature?

The treadmill desk does not have an incline feature. If it did, then the correct height of the desk would be altered during incline and would affect the user's ability to productively work. Remember, the treadmill desk is not a substitute for daily exercise. It is designed specifically to combat the hours we spend sitting. Sitting, or being sedentary, for extended hours has been linked to numerous health risks. Our bodies were made for movement and our goal in designing this was focused on just that.

 Is the desk included?

No. The TR5000-DT3, TR1200-DT3 and TR800-DT3 are treadmills design to work with most standing desks on the market, converting it into a walking desk. We do not endorse any specific brand or model of standing desks. We do however offer a complete desk and treadmill combination in the TR5000-DT5, TR1200-DT5 and TR800-DT5 in the Treadmill Desk pages on this site.
