Why are Under-Desk Treadmills Becoming Popular?

Due to the pandemic, many businesses have their employees working from home. And many gyms closed or had capacity limits on how many people could be in the building. Employees are finding out that they can work and exercise at the same time with an under desk treadmill. On a normal treadmill, there's no tabletop to type or write. But an under-desk treadmill fits under your desk. With this setup, you won't necessarily need a new desk if you own an adjustable standing desk. If your desk is wide enough, you can keep your treadmill under your desk and switch from standing to walking by just moving your keyboard or laptop.

An under-desk treadmill doesn't have arms and a console as you can rest your forearms on your desk. It's designed to be used at low speeds as you won't be able to write or type while running. Working while walking is a great way to burn calories and avoid the many dangers of excessive periods of sitting.

Why use an Under-Desk Treadmill?

Under-desk treadmills are for people that already have a desk and don't need to buy a treadmill base/standing desk combination. Now that standing desks are becoming more popular, even more people are using treadmills to work. Many people have found that using a treadmill while working is a great way to burn extra calories, increase productivity, avoid back pain from sitting for long periods, and improve their mood.

Can I Use a Regular Treadmill Under My Desk?

Running or jogging treadmills are designed to be used at medium to fast speeds. Using them at lower speeds stresses the motor and increases the chances of the motor failing.

Under-desk treadmills are designed for use at low speeds and, if maintained, should last for a long time.

How to Use a Treadmill Desk

  • It's recommended that you walk 1-2 mph while working. Walking faster than that can make it difficult to type or use a mouse, and you could get sweaty while at work.
  • Use shoes that promote good posture, that are comfortable, and won't damage the treadmill belt.
  • Many users will rotate between walking on their treadmill, sitting, and standing in a normal workday. Some activities lend themselves more to walking, such as talking on the phone, reading, or watching videos, and others that require more intense concentration are better done sitting or standing.
  • Another option is to purchase a standing mat that you can place on top of your treadmill so you can stand when not walking. Keep in mind that this will often add 2" or more to your height, so make sure your desk can accommodate the extra height. If you have to look down at your monitor because the desk is too low or lean forward to type, you could end up with back and or neck pain.

Under-Desk Treadmill Frequently Asked Questions

Here are our answers to some of the most frequently asked questions about under-desk treadmills.

Yes, but it's recommended that you use an under-desk treadmill that has two support arms on the side and the console in front so you can grab onto or rest your arms on.

What is the best under-desk treadmill?

It depends on your budget. Criteria you can use to evaluate one can include the motor, belt length and width, console, customer rating, maximum user weight, warranty, and customer service.
