JLL S300 Home Treadmill Review

In a world where home workouts and home gyms are constantly growing more popular, the treadmill is always the backbone of home fitness. Treadmills are great for shredding fat, toning muscles, physiotherapy and even stress relief. Today we’re looking at JLL Fitness’ pride and joy…The JLL S300 Folding Treadmill.


There are so many things to consider when looking at purchasing a home treadmill. These days’ treadmills do everything from playing your favourite movie to making your breakfast for you. With this in mind, it’s important to ask yourself, “What do I want from my treadmill?”. You can spend a lot of money on a treadmill, when a treadmill half the price could exactly the same job. So it’s important to keep in mind the features that you require your treadmill to possess.

This is why the JLL S300 is so popular amongst treadmill users. For the low price of £379.99 it offers a wide variety of features that many treadmills on the market don’t have.

The numerous features on the JLL S300 mean that the treadmill adapts to any user. This means that no matter what your fitness level or goal, this treadmill can adapt. The high levels of incline and speed settings mean that an advanced runner training for a marathon will be happy with this machine. Alternatively, somebody recovering from injury and needs a slow walk will be more than happy with the digitalised motor feature which provides a smooth start and a slow speed.

S300 Features

A good incline setting is a must have for any self-respecting treadmill. This is where the JLL S300 comes into its own, offering 20 levels of incline settings. The standard incline settings on most treadmills is 15, meaning with the JLL S300 gives you that distinct advantage over its competitors. The extra 5 levels of incline mean you’ll be able to push yourself that much further and intensify your workout more than ever before. As I mentioned before, the varying levels of incline combined with the advanced speeds of this treadmill mean that this treadmill would suit advanced users that are looking for a good treadmill workout or even if they’re training for a long distance run such as a marathon.

The JLL S300 is equipped with an 1800-watt digitalised motor which is more powerful than your standardised home treadmill. This powerful motor provides 2.5 CHP and the digital control means that it runs smoother and quieter than your average motor. So now the neighbours will be happy with no noisy treadmills to put up with.

The spacious running board also offers a large area for you to participate in your workout. As home treadmills go, the larger area of 123cm x 41cm is greater than your standard home treadmill and will provide you with a huge amount of room to tire yourself out.

One of the biggest fitness trends of 2016 is the HIIT workout. These workouts are great for fat burning which is why they’re all the rage. The JLL S300 caters to that and offers a digital heart rate programme. This provides the user to set a standard heart rate that they want to adhere to and the treadmill will speed up or slow down depending on where your heart rate is. Forget your smartphone…this is a smart treadmill!

Of course any foldable, transportable treadmill would be useless if it wasn’t foldable or transportable. The JLL S300 doesn’t disappoint here with its feather like soft drop feature that allows the treadmill to fold up and down with minimal effort. The handy transportable wheels also mean that the treadmill can easily be transported around the home, although a JLL top tip would be to assemble the treadmill on the floor that you wish the treadmill to stay.

The JLL S300 provides 15 running programmes of which 3 of them are customisable. This gives a greater sense of versatility than with your average treadmill. You can build the treadmill workout to tailor your workout and can provide yourself with the most realistic outdoor running experience ever!

The entertainment system isn’t too shabby either. The S300 comes equipped with auxiliary and USB connections meaning you can plug your tablet, smartphone or MP3 player into and enjoy your workout playlist through the powerful speakers located on the console.


Three things are a certainty in Britain; death, taxes and that it’ll rain. Home treadmills are becoming ever more popular because of this… (because it rains a lot, not because of death or taxes). Home treadmills give you the opportunity to run and get a good workout in when the weather doesn’t look too appealing outside. And with the latest technology on the JLL S300, outdoor running has never been more accurately simulated.

Treadmill running isn’t comparable to outdoor running. You can sprint for longer on a treadmill meaning that they are great for HIIT workouts, which aids in fat burning. A HIIT workout on the treadmill will provide you with high periods of fat burning so it’s great for getting lean. Next time you’re at the gym or on your home treadmill, try this HIIT treadmill workout:

  • 40 seconds at a high pace (almost sprinting), followed by 20 seconds of rest. Do this 10 times over a 10-minute period

The S300 is digitally controlled giving it a greater advantage against its opposition.

So whether you’re looking to use your home treadmill to workout with HIIT sessions, warm up, physiotherapy, train for a marathon or even go for a gentle walk when it’s raining outside, the JLL S300 home treadmill will cater to your needs. This incredibly versatile folding treadmill will be everyone’s go-to fitness tool.
