Further down the page, you’ll find some explanations regarding the key similarities and differences between the ProForm 400i and the ProForm 600i.
But before checking out explanations regarding their specs and features here’s a table that summarizes the main technical summary sheet for these 2 treadmills:
Specs Comparison
Before we discover more details of each product, let’s look at the price of each product. The ProForm 400i costs 400$ less than the ProForm 600i. However, you haven’t seen the affordable side here yet.
What about the dimension? The ProForm 400i has a dimension of 65.77″ long,32.75″ wide, and56.42″ high. The ProForm 600i is bulkier with a longer dimension of 82.5″ long, 30″ wide, and 13.3″ high.
How much does each item weigh? The ProForm 400i weighs 272 Lbs. On the contrary, The ProForm 600i is 30 lbs lighter. But here comes the surprise. Although ProForm 600i only weighs 224 Lbs, it can hold up to 325 lbs. It is a surprise to know that the ProForm 400i can only sustain the weight of 300 lbs.
What about the number of training lessons? Both treadmills are installed with the iFit Coach package which can be subscribed to through your credit account. For ProForm 400i, you can easily select the package via Bluetooth Smart connection. For ProForm 600i, you can have access to Google Maps to vary your training route.
Are you curious about the engine of each product? For this round, ProForm 600i has a stronger motor that can produce 2.75 Horsepower. Meanwhile, ProForm 400i is run by an adorable 2.0 CHP motor.
Is the cooling system of each treadmill efficient? Unfortunately, the ProForm 400i lacks this accessory. However, you might want to try the CoolAire Fan on the ProForm 600i.
Let’s discover other options each treadmill can offer you. For both of these ProForms, you can have an EKG Grip Pulse Sensor which can be an assistant in monitoring your heart rate. You can simply lean on these hard plastic grips for an automatic heart rate calculation.
The other detail which we recommend for your review is the incline/decline range of each treadmill. In this round, ProForm 600i again wins with a maximum angle of 12% incline. It is generally known that greater incline range will become an asset to strengthen your muscles.
The treadmill belt of the ProForm 600i is greater in length than the ProForm 400i. The ProForm 600i is 60″ long which wouldn’t reduce your stride. It is unfortunate to know that the ProForm 400’s length of tread belt is shorter than most treadmills by 50 inches.
The footprint of each tread belt has the same thickness. In addition, ProShox Cushioning technology is applied to minimize shock and protect the runner’s joints. The ProForm 600i has a more durable footprint than the Proform 400i which can reduce maintenance fees and increase safety.

Features Comparison
How fast can you run with these machines? For ProForm 400i, you can run up to 10 miles per hour. On the contrary, you can run up to 12 miles per hour with the ProForm 600i. However, no one wants to run that fast. Therefore, the engineers have designed a simple leveraging scale that can be switched at ease with manual buttons.
Exciting news for ProForm 600i buyers is that you can be offered 22 built-in workout apps and hundreds of programs from iFit Coach. But you can only be given 50 built-in workout programs with the ProForm 400i.
These programs can be selected by a Quick Touch technology if you train with the ProForm 600i. While you still need to adjust your incline/decline range by clicking on buttons manually on ProForm 400i.
Your training session can’t be exciting without quality sound. Both treadmills are equipped with an Audio Auxiliary Port w gate. After you’ve connected your smartphone via Bluetooth or plugged your headphone cord through the jack, your music will be played on Dual 2″ Speakers. Unfortunately, neither treadmill is equipped with a USB gate.
A small drawback for the ProForm treadmill is the Round Watt Meter Display Screen. Although the data is shown with LED light, runners sometimes find it hard when looking for their outputs such as their heart rate, calories burned, incline/decline range.
However, the biggest innovation might come from the device holder. For the ProForm 400i, you can put your smartphone or tablet on the tray in front of you. The ProForm 600i offers you a device grip tray that only fits your smartphone. This firm grip helps you watch your favorite videos at ease.
On the water bottle holder, you can put your bottles on both sides of each treadmill. The small holes enable you to put the bottles in an upright pose but not in whichever size you want.
For ProForm 600i, you can have a lifetime warranty for the frame and motor. ProForm also offers you a two-year parts warranty and a one-year warranty for labor.
The ProForm 400i also has a lifetime warranty for its frame. But there is an additional 25-year warranty for the motor and a one-year warranty for labor and parts.
