Treadmill Review

Today, people are increasingly becoming conscious of their health situation. So they found ways to stay healthy and maintain a good size. One of the means of achieving these goals is exercise. Walking and running on a treadmill is a practical form of exercise for almost everyone. The machine has all the basic features you’d expect from a treadmill and brings some surprises, like downhill training and an innovative suspension system.

Making treadmills affordable is not an easy task. It is necessary to design the machine to meet the needs of the target customer base while maintaining an affordable range. ProForm is one of the few brands that has mastered the difficult task of producing decent quality, budget treadmills.

ProForm Performance 400i is part of a low-cost treadmill range that also includes Performance 400c, 600c, and 600i. An “I” in the model name indicates the treadmill is iFit-enabled; it can connect to the tablet and show iFit programming. The 400-level treadmills have 55-inch tracks, and the 600-level treadmills have 60-inch tracks.

The Performance 400i is designed for pedestrians to increase calorie consumption and has a maximum incline of 10%. The Proform 400 folds down to save space. There is an impact-assisted folding mechanism that reduces tension on the back, and there are also rollers on the underside for ease of movement. For pedestrians, it offers an affordable way to practice indoors and in virtual travel around the world with Google Maps Training ™. 

While it will give you a good foundation, you won’t actually get any of the fun bonuses that Proform is so good at on this treadmill. There is no iFit LIVE, no web browser, or a funky backlit console. Some people don’t really care about all of this. They just want a treadmill they can walk on. 

The car is designed for pedestrians, not runners. This is a step up from the Performance 400c, which requires the separate purchase of an iFit monitor. The advantage of the treadmill in this review is that iFit programming can be viewed on the tablet.

Why is PROFORM PERFORMANCE 400 TREADMILL your perfect workout partner?

The ProForm Performance 400 treadmill can help you reach your health and fitness goals. It features built-in workouts programs that you can use for your daily workouts. While they’re not at the highest level, you’ll get a simple and good basic build on this treadmill, including a decent motor, a relatively large belt, and one of the newer suspension systems that will give you joint protection.

This treadmill uses “ProShox” damping. The cushion system compresses with each step and responds evenly to your step, providing a truly comfortable workout.

The most important areas to consider include:

  • Drive system: the importance of quality and size of the motor with respect to the thickness of the belt, the size of the rollers, etc. When assembled well, a treadmill can be great. If the engine makes a loud hum during operation, it usually means it has a high speed, which means it wears out much faster.
  • Deck: The deck lasts quite well and can often burst. If the treadmill is light, it usually means the bridge isn’t too thick. The sturdy frame and plate have a big influence on the overall feel and noise of the treadmill.

Workout Programs:

To stay motivated and reach your maximum potential while using the treadmill, it is important to have a range of built-in workouts programs available. This treadmill scores points here with a total of 18 predefined workouts.

The 18 predefined fitness training programs are divided into three functional groups, which consist of: 5 calories burned, 5 measured times, 5 distance workouts, and 3 inclinations. Each of these programs has been designed to help you reach your fitness goals as quickly as possible.

QuickSpeed Controls:

This model is equipped with a “QuickSpeed” control. This means you can easily switch to any speed with just one tap during your workout. Immediately decrease the speed when you need a break or increase it immediately in the event of a severe explosion.


We view incline training as a game-changer on a treadmill – you can literally prepare your body for challenging uphill runs. The incline workout adds resistance to your daily workout, burns more calories, and increases muscle tone. 

The Performance 400 offers automatic tilt adjustment. When you train on an incline, you know that you give your feet the best possible workout on the treadmill. The display on this treadmill has an LED display with multiple windows. LED display elements are more legible than LCD displays and make training tracking much easier. 

This display tracks your speed, time, distance, and calories burned so you can track your progress as you exercise.

Heart Rate Monitor:

The treadmill is equipped with a Dual-Grip ECG heartrate monitor. Built-in precision sensors allow you to quickly and accurately monitor your heartrate. Just grab the built-in sensors to quickly and accurately track your heartrate, stay in your optimal training zone, and help burn more fat. 

Training data is displayed on the Watts LED, the new ProForm display for 2016. The Watts LED resembles a car speedometer and has a circular output that shows your energy output. Inside the circle is a window that can display elapsed time, grade level, and other statistics.

Tablet Holder:

Above all, the console is a tablet holder that you can use to hold the tablet. So you can go online and browse the web or watch your favorite shows or movies as you walk. The only downside is that the tablet holder isn’t as adjustable as the tablet holders on other treadmills, like the Proform 600. But it sits at eye level, so it should be fine for most people.

Is the PROFORM PERFORMANCE 400 TREADMILL good enough for your cardio?

For someone who will just walk … and won’t do running too much, or you’ll need a doctor on a treadmill. The Proform Performance 400 hardly leaves a mark for determined pedestrians, and we cannot recommend it to runners. Service and parts replacement are very likely to cause short-term user error, and Icon’s poor customer reviews service will be a cause for concern. Some of the people who bought and used this treadmill have had a hard time getting it to work. However, the concerns are small and were easily resolved. Serious runners need to focus on higher quality treadmills priced from $ 1,500 and up to get good results. If you are a serious user, seriously leave the car. If you are planning to breastfeed and take care of how we propose it, it is on the edge of whether it will work in the long term.


The 2.25 CHP engine is not that impressive. It has an axial fan, which extends the running time but does not support serious operation or runs very quietly. The maximum speed of the treadmill is 10 mph. By comparison, the top-of-the-range ProForm Performance 1450 has a 3.25 CHP engine with a lifetime warranty.

Decision: Should you invest in a PROFORM PERFORMANCE 400 TREADMILL?

If you are looking for a super affordable treadmill that offers you the best entertainment options on the market, you will love the Proform Performance 400 treadmill. In terms of the number of features and functions, it is definitely among the top of its class. This machine gives you quality above average in most respects. The warranty isn’t as great as you’ll find on more expensive treadmills, but it offers more than you’d expect on a treadmill. 

With the various experiences and observations of many owners and users of this treadmill model, it is still worth considering. Overall, it is a good treadmill with useful and useful features. If you decide to get fit and be pink, you might want to consider this treadmill. However, it is always convenient and practical to fully control the unit if possible; the first test if you are actually walking or running on it.
