When I set up my home gym, I got various equipment to make it easier to variate and enjoy on days that workout becomes challenging. So, when I got a treadmill, I was looking forward to using it and enjoyed running on it just to see my sweat producing and helping me burn calories.

But it has been a few weeks, and everything has been going well except today; I just felt my treadmill moving or shaking, which felt very dangerous to continue running. Therefore, I immediately unplugged it and opened my laptop for a quick search on what caused it. 

Many treadmills can generate problems even after regular maintenance and working well. Now these problems are new topics I need to look up and see if it is safe to keep using them.

Why Does a Treadmill Moving and Shaking?

Improper Assembly

One of the primary reasons for a shaking treadmill is improper assembly. If your treadmill is not assembled correctly, it may be wobbling, and the belt may not be centered. 

To alleviate this issue, it’s essential to have your treadmill professionally installed and assembled. This will ensure that the equipment is put together correctly and you don’t have any issues with your treadmill shaking or moving while in use.

Uneven Flooring 

Another common reason for a shaking treadmill is uneven flooring. If your floor is not level, your treadmill may wobble and shake, and this can be dangerous, especially if you’re running at high speed. 

If you have carpet, you may also notice that your treadmill moves or shifts around. To correct this issue, place your treadmill on an even surface and use a treadmill mat to help reduce any movement caused by the flooring.

How Do I Know There is a Problem

If your treadmill is acting up, there are a few things to check to determine the problem. If the speed is inconsistent, there might be a problem with the belt or the motor. 

  • A slipping belt is another common issue, which can be fixed by tightening or aligning the belt. If the display isn’t working, it could be a problem with the power cord or batteries. 
  • A burning smell could indicate a more severe problem, so turning off the treadmill immediately is essential. A non-working motor may need to be replaced, which can be expensive. 
  • Lastly, if the belt heats up too much, it may need to be lubricated or replaced. While some problems can be fixed quickly, others may require professional attention. It’s important to troubleshoot and fix the problem correctly to avoid injury and damage to the machine.

How Do I Stop The Shakes and Moves?

It is essential to find a proper solution to get rid of this dangerous problem you have developed because it’s not even about you being unable to run on it. It has now become about what if you run and fall? 

Or what if it damages the equipment and your treadmill is now weary of use because the bolts or the motor broke down? And you’re helpless because it costs a fortune which is around $200 onwards, depending on the hours. 

But the best approach to eliminate all these frustrating problems is simple. Know better, and well, don’t assemble the treadmill on your own because, ultimately, workers have to come and install it.

Professionally Installing Treadmill

Installing a treadmill properly is essential to avoid any damage or problems down the line. While it may be tempting to install it yourself, it is recommended to have it installed by a professional. 

This will ensure that the treadmill is leveled correctly and positioned in a suitable location with adequate space and access to an electrical outlet. A professional will also ensure that all the components are assembled correctly and securely, minimizing the risk of any malfunctions or accidents during use. 

A professional installation may also come with a warranty or service agreement, providing peace of mind and additional protection for your investment. 

A good labor warranty can make safe use of a treadmill for up to 2 years, and a bad one can even be only for 90 days, so you also need to ensure that you have the right laborers and a long-time treadmill machine.

Self-Installing a Treadmill

Self-installing a treadmill can save you money and give you a feeling of achievement, but it’s vital to take the time to read and follow all instructions to avoid damaging the equipment or causing injury. 

Begin by clearing the space where you plan to install the treadmill, ensuring enough room to comfortably walk or run on the machine. Check all the parts to ensure that nothing is missing or damaged, and ensure you have all the necessary tools to assemble the treadmill. 

Follow the step-by-step instructions carefully, and if anything is unclear, consult the manufacturer’s website or customer service. Repeatedly check all connections and ensure everything is tightened securely before testing the machine. 

By taking the time to install the treadmill correctly, you can ensure that it functions safely and effectively for years to come.

So, when you purchase a treadmill that already costs plenty, ensure that the workers install it according to all the instructions, and if you decide to self-install it, make sure you go through all the instructions on the card and settle it on an even surface to enjoy and run on your treadmill without any potential challenges except to burn calories. 


Maintaining and troubleshooting your treadmill is essential for its longevity and safety. Regular maintenance and proper use can prevent many common treadmill problems. 

However, if issues arise, it’s essential to identify and address them promptly to prevent further damage and potential safety hazards. Following the manufacturer’s instructions and seeking professional help can ensure that your treadmill remains in good working condition and provides a safe and effective workout experience. 

With the proper care and attention, your treadmill can continue to be a valuable asset to your fitness routine for years.
