How Hard Is It To Put A Treadmill Together? Let’s Find Out!

Is It Hard To Assemble A Treadmill?

If you have ever built an exercise machine, then you probably already know that it can be quite difficult.

Treadmills are a popular piece of home fitness equipment. They’re often seen in gyms and running clubs. The benefits of treadmills are endless, but building one yourself can be tricky.

You might think that it’s much easier to buy a pre-built model, but if you’ve built nothing before, you’ll find that putting one together yourself will be a lot easier.

All the pieces of a treadmill are very simple, yet putting it together can feel overwhelming and even stressful. But don’t let this worry you!

The most crucial component (the frame) is simple to put together, but for the other components, the instructions will vary depending on the treadmill manufacturers.

Putting a treadmill together can be a pretty big job. If you’ve never done it before, you might find it quite daunting. In this guide, I’ll show you exactly what you need to do to assemble a treadmill.

So, let’s start!

How do you put a Treadmill Together?

If you are considering having a treadmill put together for your home, you should know that this is no small task.

The total cost involved in getting a treadmill for your home can vary depending on several factors. The price depends upon the size of the unit.

If you need extra space or larger components than the prices may be higher than average. However, if you only require basic features like a standard width/length then the costs will not be high.

You can check online or ask around when buying a treadmill from your local retailer.

To get started, measure your space where you plan to place your new treadmill. You want to make sure that you choose a location that has enough room for all the parts involved in assembly.

This includes:

  • Space around the perimeter of the floor/ground
  • Room underneath the unit
  • Enough clearance from walls and furniture

Take out any old appliances or heavy objects that won’t fit inside the area you chose. Then, remove any carpeting or padding in order to give your feet some traction when walking.

Finally, turn off electricity to ensure no sparks happen during construction. Below are the tips on treadmill assembly.

Step 1: Frame Assembly

First things first – we begin with assembling the base or frame of our treadmill. This part may seem like a fairly straightforward task, however there are many ways to go about doing so.

After unboxing, take the time to read through the instruction manuals for treadmills thoroughly. There should be clear pictures showing each step involved in setting up your treadmill.

Follow these steps until you finish installing the frame onto its stand.

It all depends on how your frame is constructed. Some frames come as two separate parts which must be assembled together; others are made up entirely out of metal tubing.

Whichever method you choose, make sure that you follow the assembly instructions carefully.

Step 2: Attaching wheels and casters

Once your frame is set up properly, you can move on to attaching the wheels and casters. These are usually attached by simply screwing down into place.

However, some models require drilling holes in order to secure the wheel/caster mechanism. Again, refer to the instructions provided when buying your treadmill.

Remember that they aren’t always consistent between brands. Once you attach the casters, try moving around the frame to check whether it feels comfortable. If not, adjust where necessary.

Step 3: Installation of the deck

Next comes the installation of the deck. Depending on the style of treadmill you purchase, you may only need to install the top portion of the platform.

Others require both sides to be installed. Check the instruction sheet included with your treadmill to see exactly how to proceed. With the deck in position, flip over the treadmill and tighten all screws securely.

  • Make sure everything fits well without wobbling.

If you have trouble finding the right spot to secure the screws, use an electric drill to bore small pilot holes into the wood.

This allows you to insert screws more easily.

You’ll also notice that some treadmills come equipped with a safety bar for added stability. Although optional, if you decide to buy one, follow the instructions carefully. Otherwise, just leave them as-is.

Step 4: Installing the treadmill belt

Now that the frame is complete, we’re ready to add the belt. The belt attaches directly to the motor pulley system via two metal brackets. Be careful while tightening the bolts; too much force could damage the motor.

Again, consult the manual for detailed information regarding which type of belts are compatible with your model. Some people prefer using chains instead of belts, though.

Step 5: Setting up the running program

The last thing left to do before putting your new machine to work is to program the running software. This will allow you to choose what speed, treadmill level and incline you want your treadmill to run at.

You might even find different programs based on user preference. Again, refer to your owner’s manual for details about this process. 

Step 6: Enjoy!

You’ve completed the final stages of assembling your new fitness device. Congratulations!

Now, get started enjoying the benefits of working out on your brand new piece of equipment.

Remember to keep yourself safe, however, so make sure you wear proper footwear and stay hydrated. Have fun exercising!

What tools do you use for Treadmill Assembly?

There are various tools that are used for the assembly of a treadmill. These tools are necessary to assemble a treadmill. Usually the tools include;

  • A wrench
  • Screwdrivers
  • A socket wrench set
  • A torque wrench
  • Allen wrench
  • Hammer
  • Ratchet
  • Allen key

When assembling a treadmill, you would normally start by attaching the flywheel to the base with the flywheel bolts.

Use a wrench to tighten the screws and screwdriver to remove them. A drill will help you get the holes for screwing the parts together.

And a rubber mallet is needed for the assembly of the parts to a full treadmill.


Each treadmill is different and requires specific steps, but the same principles apply. Start by following the instructions in the manual, which should be included with your treadmill.

If you have lost the manual, you can find one online. The manufacturer of treadmills’ website or the consulting the resources on the product page of the manufacturer’s website.

You can also find tips and videos on YouTube and other online resources. These together can help you.

I would recommend that you have someone who can put treadmill together before and get them to help. The assembly process is easy, but it’s easier with two people.  If you do it yourself, then a power screwdriver is an absolute must.
