Cushion System

The cushion system on the JLL T350 is one of the best features because treadmills, in general, are more challenging on your joints than stationary bikes or ellipticals. That’s why you and many other people may avoid getting a treadmill: you think it will ruin your joints or cause more pain.

However, weight-bearing exercises are essential to keep your bones healthy.

Fitness bikes are excellent for weight loss and toning, but only treadmills ensure you won’t lose any bone density, which usually happens as we age.

Luckily, JLL T350 has a 16-point cushion deck that absorbs any impact to your knees and ankles. That way, anyone can use this treadmill, even the elderly or people recovering after surgery.

And there’s another advantage:

This cushioning system protects you from pain and strain so that you can work out harder for longer.

20 Levels of Incline

These many levels of incline allow you to challenge yourself appropriately according to your fitness level. You can start up small and work your way up to a steeper incline.

Besides, you can mix-and-match the levels of incline throughout your workout. For example, you can start with grades 2-4 for your warm-up, go up to 15-20 during your training, and cool down on a level 1 incline.

You can change the incline levels quickly with just a push of a button. Therefore, you can use the JLL T350 for HIIT because you can vary the incline levels smoothly.

But you don’t have to do HIIT on this treadmill if you don’t want to. Here’s why:

The higher the incline level, the more calories you’ll burn. According to JLL, you can burn as much as four times the fat calories by merely walking on a higher tilt.

And, of course, that means the JLL T350 is a reliable piece of equipment to lose more weight and build more resistance through low-impact workouts.

Motivating Entertainment

The JLL T350 has all the bells and whistles regarding entertainment, except one.

Here’s why: this treadmill has a USB interface for your iPod, iPhone, and MP3 to play your favourite tunes. That way, you won’t have to use your headphones while you’re running, which can feel really uncomfortable when you’re doing high-impact workouts.

But there’s a problem:

You can’t plug in your tablet. Technically, you can, but most tablets are large enough to cover the screen. And you need that screen to see your stats or make adjustments.

The alternative is to use the Bluetooth connection for your tablet and place it on a stand nearby.

State-of-the-art Console

jll t350 console

The console is intuitive and easy to use thanks to the pressure-point technology that’s arguably better than buttons, which eventually wear out.

All you have to do is tap on the function you want, such as audio, program, speed, o incline. All the info and actions you need are visible and within easy reach.

Besides, the LED display is large, legible, and backlit. The screen tells you stats like time, speed, distance, incline, and calories.

You can also read your heart rate so that you can adjust your workout difficulty according to your pulse. That way, you can reach your fitness goals faster.

We’ll talk more about this option below.

For now, here’s a disadvantage:

The speed and distance are measured in km/h and km, respectively. So, if you’re operating with American measurement units, you’ll go through a steep learning curve.

Heart-rate Measurement

The pulse plates on the arms are easy to reach, without bending forward uncomfortably.

Besides, the JLL T350 has a particular heart-rate workout that varies the speed automatically according to your heart rate.

As you can see, there are two disadvantages:

Firstly, the heart-rate programme only changes the speed according to your pulse, not the incline. That option may not suit you if you prefer low-impact exercises.

Secondly, you need to keep your hands on the treadmill’s arms to get those heart rate measurements. But this can feel a bit uncomfortable if you prefer to move your arms or hold on to weights as you exercise.

20 Workout Programs

The wide array of workout programs is especially useful if you’re a beginner. Thanks to these pre-programmed workouts, you can easily find your rhythm and discover what works for you.

Afterwards, you can customise your own routines depending on what your body needs, your goals, and what motivates you.

But there’s another advantage:

The JLL T350 comes with a program booklet that helps you burn more body fat, tone faster, and improve your conditioning. You can work through your Progress Plan to see how much you’ve improved your fitness level.

JLL works with experts to create these Progress Plans, which means you’ll benefit from effective workouts.

Wide Speed Range

JLL T350’s speed range varies between 0.3 and 18 km/h. As such, this treadmill has one of the highest maximum speeds for home treadmills so that even expert runners can use it.

The 18 km/h speed is excellent for fat burning because your heart rate will skyrocket. However, you can still challenge yourself at lower speeds if you increase the incline.

There’s a problem, though, apart from the fact that the speed is displayed only in km/h:

The noise levels.

JLL claims that the T350 is quiet and smooth even when you’re pushing yourself at maximum speeds. However, a few reviews state the contrary.

That’s because the cable needs to go through the treadmill to connect with the console. Some customers found that bit challenging because the line keeps bending. Besides, if you don’t do it properly, the treadmill can make an irritating noise.

Moreover, other people claim their belts became loose within weeks of use, and that made the belt noisy. The solution is to address customer support, but we’ll discuss that below.


jll t350 folding treadmill review

The JLL T350 is a heavy-duty piece of equipment, but it fits your at-home needs. If you don’t have a separate room for your gym, know that you can fold and transport this treadmill quickly.

The Soft Drop Technology activated with a hydraulic arm, allows you to unfold and fold the T350 smoothly. After your workout, lift the treadmill on the transport wheels to move it to a storage place or to a corner of your home where it doesn’t inconvenience you.

JLL T350 takes most people’s space requirements into account even when the treadmill is unfolded.

As such, the unfolded occupying area is 158 (l) x 70 (w) x 128 (h) cm. The running platform is 121 x 41 cm so that you have ample space for running even if you’re tall and heavy. Remember that T350 allows maximum weights of 120 kg.

But some space-challenged customers noticed a problem:

You can’t use this treadmill if you detach the frame because the cable that runs from the base is what allows you to turn it on. Of course, the option of using it without a stand would have been best if you want more convenient storage.


JLL T350 offers a 2-year warranty for parts and labour, a 5-year warranty for the motor, and a lifetime warranty for the frame.

However, you need to keep the JLL packaging if there are any problems and you need to return the treadmill. Remember that JLL only refunds about 80% of the original cost without shipping and reshipping fees if the T350 is otherwise functional, but you simply don’t like it.

You may also need to take photos and videos of the malfunction for proof.

The biggest problem, according to some customers, is that the JLL customer service is dismissive because the support staff didn’t answer or return their calls promptly. Besides, they have many rules about returning an opened product instead of focusing on their clients’ needs.

In Conclusion

JLL T350 is a heavy-duty, reliable treadmill for all sizes, shapes, and fitness levels. This piece of equipment has all the bells and whistles to keep you motivated and in good form.

You can change between 20 incline levels, 20 workout programs, and run as fast as 18 km/h, plus you can follow the Progress Plan to attain your fitness goals quickly. Moreover, the cushioning platform and USB connectivity will help you stay pain-free and motivated for longer workouts.

JLL T350 fits in most homes because it’s compact, although its running deck is generous.

But T350 isn’t free of issues. Some customers found it challenging to install, the speed and distance readings are displayed in kilometres only, and the support staff isn’t the friendliest bunch.

But none of those things affects T350’s functionality.

Compared to other treadmills, T350 protects your joints and gives you all the necessary resources to train effectively. And it will last you for years, so it’s a good investment.
