LifeSpan Fitness TR4000i Folding Treadmill Review

LifeSpan Fitness TR4000i Folding Treadmill Review

One of the simplest ways to burn fat is to run on a regular basis. Brisk walking can also improve your health. Cardio is the cornerstone of fitness regimes all around the world. Cardio provides too many health benefits to mention in this article. The point is that, in order to lose weight, one should begin with cardio.

But, most people don’t want to exercise. It’s exhausting, and your muscles are sore afterwards, it’s not comfortable. Gyms are often uncomfortable for a number of different reasons. Maybe there are too many bodybuilders in the gym and that makes you feel insecure because you are not on the same fitness level. It can be extremely bothersome to deal with the judgmental stares and whispers while you’re trying to exercise. It’s distracting.

So what’s the alternative? Should you continue exercising at the gym and just endure?

I believe there is another option. Don’t exercise at that gym. It’s important to feel comfortable wherever you decide to exercise. If you’re not in a comfortable environment, it will be much more difficult to progress with your exercise routines, and positive results will be far and few in-between. What is the most comfortable environment for you? I believe its home.

Many of the world famous athletes began training at home gyms. Investing in building a home gym is an excellent decision. Of course, there are so many types of machines and exercise equipment to choose from. It can be confusing to decide where to begin and which machines to buy first.

I believe one of the most important pieces of equipment for a home gym would be a treadmill. You’ll need a top-notch treadmill that is reliable and does not take up too much space. LifeSpan has a set of perfect treadmills for home-use. One such treadmill is known as the TR4000i foldable treadmill, and it’s one of the best treadmills on the market today.

It’s a perfect piece of equipment for your new home gym. This treadmill is one of the high-end treadmills.

TR4000i Pros:

• Powerful 3.25 horsepower engine.
• Spacious running area.
• Lifetime warranty on frame and motor.
• Wide selection of exercise programs.
• Customizable exercise programs.
• LifeSpan Fitness Club Membership.
• Built-in speakers and audio jack.
• Detailed data recording.

• Maximum speed of 12 MPH – perfect for fast runners.
• Solid smooth running deck with no bounce-back.
• Exceptionally quiet.

• Simple set up and the LCD screen makes it easy for people to select programs.

TR4000i Cons:

• Some customers have complained that the device emits static electricity which can cause electric shocks. However, these cases are quite rare.
• It does not have a built-in cooling fan.
• The lighting on the console can be a bit confusing.
• The belt sometimes needs to be tightened.

In general, the model doesn’t have a lot of downsides. It’s slightly more expensive than the previous LifeSpan treadmills but it’s also much more advanced, as I mentioned earlier, it’s a high-end machine. The entire treadmill is built from high quality materials and has a sturdy – strong – feel to it. The deck is also quite hard; some customers have mentioned that the deck is as hard as a cement road.

So what features are included with this product?


In this section you’ll find a list of all the most important TR4000 features.

Top-Notch Sound System

This feature is particularly useful for people who like to listen to music while working out. The speakers are built into each side of the front control panel. The speakers come with an audio jack that you can use to plug your phone or iPod into. Many customers recommend the speaker system. The volume level is not too loud and not too low.

EZ Drop-Folding Device

The system is designed to allow people to fold the treadmill without much of a hassle. As you might have remembered, the treadmill is significantly heavy, and it would be quite difficult to fold the treadmill without this cool feature. It allows the treadmill to fold slowly without much effort; it’s also 100% safe.

Intelli-Guard Automatic Pause System

The Intelli-Guard system is a trademark feature of LifeSpan treadmills. On each side of the treadmill there are sensors which detect movement. If someone decides to remove himself from the treadmill, the sensors will detect the lack of movement, and stop the treadmill belt. It’s an excellent feature that not only improves the safety of the treadmill but it also helps to reduce electricity consumption. Think of it like an automatic standby mode. Customers who have children love this feature because it creates a safe environment for kids.

Heart Rate Monitor

The treadmill comes with a hand grip and receiver which are designed to detect heart beats and upload the data to the treadmill’s database. This feature was created for individuals who want to maintain a steady heart rate for a prolonged period of time. It’s a perfect solution to keep track of your heart rate while exercising. You’ll be able to see your current heart rate on the control panel in the center of the device.


This is another trademark feature of LifeSpan products. The treadmill is built with pressure sensors that count each time someone takes a step on the device. It’s particularly useful for people who want to keep track of how many steps they take when running. Doctors often recommend people to take a certain amount of steps per day and this feature allows people to reach the quota without much of a hassle.


Below are the technical details regarding the TR4000I treadmill.


The TR4000i is powered by a 3.25 horsepower engine which has a maximum speed of 12 MPH. The engine is powerful and smooth, there’s no need to warm up the machine.

Weight and Dimensions

I mentioned earlier on in this review that the treadmill is significantly heavy. Most shipping companies won’t want to move the treadmill into someone’s home without a generous tip. In total, the shipping weight is 235 pounds.

The dimensions of the treadmill are similar to the other LifeSpan treadmills. The following are the dimensions of the TR4000i: 74 inches long, 33 inches wide and 54 inches tall. However, if the device is folded, it’s about 42 inches long. The dimensions are the same as the TR1200I and TR3000I but the TR4000I weighs a bit more than the other products.


LifeSpan offers a lifetime warranty on the frame and engine of the machine. But there is a 1 year warranty for maintenance and a five year warranty for broken parts.


Below are some accessories that are included with this model.

Book Rack

Another LifeSpan trademark accessory, it allows people to store magazines and books to read while jogging.

Chest Strap

The chest strap is an additional device that can be used to track heart rate. If for some reason the palm strap does not work, this device will improve the accuracy of the heart rate tracking system.

Cup Holder

The cup holders on this treadmill are quite deep and are designed to hold a wide range of bottles and cups. They’re within easy access, there’s no need to step off the treadmill to get a drink.


All in all the TR4000i foldable treadmill is an excellent machine for people who prefer to work out at home. It’s one of LifeSpan’s higher-end products and it certainly meets up to expectations. If you’re looking for a reliable, sturdy, fancy treadmill with plenty of features, this product is for you.

It tracks a wide range of data and compiles it into fancy reports. It’s perfect for people who want to keep track of each aspect of a workout session. On top of that, the treadmill is safe, quiet, and it operates smoothly. If you’re planning on creating a home gym, consider purchasing this treadmill.
