Build quality

The JTX Zenith Cross Trainer is deigned with solely performance and usability in mind, without the frills and gimmicks that raise the price. What you will find are top quality components. This makes it a stable, sturdy, professional machine that will deliver great performance over many years.

Ergonomic design

The Q-factor on a cross trainer refers to the distance between your feet when you train. It is important feet are the correct natural distance apart to make operation as comfortable as possible. On this machine the Q-factor is 15 cm, providing perfect comfort and alignment as you exercise.


Functional design

The multi-grip handlebars are ergonomically designed to provide maximum use of the upper body from a bio-mechanically correct position. You have the option of using the moving handles with upper body to propel you, or holding on to the fixed handles for support and greater focus on the lower body.

Stride length is comparable to gym machines, at 53 cm (21 inch). This means you can work hard and really stretch out your legs to maximise your fitness goals.

The finish is simple and stylish, with a matt black paint job and zero clutter. It would look the part in any home gym.


The 17 kg flywheel is part of a magnetic resistance system designed to provide optimum performance and a smooth, quiet ride. Its weight and configuration are crucial to the quality of its movement. There is a large resistance range with 16 levels providing a work out that can challenge beginners or advanced users alike.
