JLL S300 Digital Folding Treadmill Detailed Review

JLL S300 Digital Folding Treadmill Key Features

LCD Display Monitor

The JLL S300 Digital Folding Treadmill comes fitted with a high-quality LCD display.

This display allows users to monitor their heart-rate, speed, distance covered, calories burned and time passed. 

This allows runners to check their progress, stay motivated and assess post workout performance.

The LCD console can also be used to select one of the JLL S300’s 15 pre-set running programs. Three of these programs can be customised to provide a more bespoke workout experience. With the JLL S300, you can mix things up on a regular basis to achieve your individual fitness goals.

Heart Rate Sensor Handrails

The JLL S300 Digital Folding Treadmill incorporates two ergonomically designed hand rails. However, these are no ordinary hand rails. They also double up as pulse sensors with the ability to change both speed and incline level.

Pulse sensors are rare in folding treadmills, so the JLL S300 Digital Folding Treadmill is unique in this respect. Pulse sensors can be effectively utilised to assess post workout recovery. The faster you heart rate returns to its normal resting rate, the fitter you are becoming.

20 Power Incline Levels

The JLL S300 Digital Folding Treadmill allows the user to vary their workouts and push themselves further with 20 levels of power incline. This can be adjusted using the treadmills handrail controls.

This allows users to incorporate more difficult forms of training such as HIIT and uphill running. Walking/running at an incline not only provides a more challenging workout. It also allows users to more effectively sculpt their calves, glutes and hamstrings.

Entertainment Centre

To help keep up your energy levels the JLL S300 Digital Folding Treadmill comes with a built-in media centre. This allows users to play music through two high-quality speakers. Simply connect your mobile or mp3 device via USB or Aux connection to listen to your favourite workout playlist.

16 Point Cushion Deck

The JLL S300 Digital Folding Treadmill’s running track comes with a 16-point cushion deck. This deck absorbs the impact of the user’s feet while running like a sponge. In turn, this minimises the impact on the runner’s knee and hip joints. Making indoor running using a treadmill a much safer alternative than running on concrete.

2 Year Warranty

To ensure you get your money’s worth, JLL offers a 2-year parts and labour warranty. This means that should you experience any mechanical difficulty with your S300 within 24 months of purchase, JLL will correct the problem at no monetary cost to the user.

In addition to this warranty, the JLL S300 Digital Folding Treadmill’s motor comes with a 3-year guarantee.
