kBox4 Lite System

kBox4 Lite systems include the mid-range kBox model, perfect for users who frequently travel but refuse to compromise on their training.

Due to its low weight, at just 9.5 kg, and incredible capabilities, including the built-in kMeter II feedback system, the kBox4 Lite is a hit among travelling teams and all kinds of facilities who wish to make the most out of their floor space.

A list of accessories included with each kBox is shown in the Description tab below.

Available in a choice of three colours. A member of our team will contact you once your order is placed to confirm your colour choice.




The kBox4 Lite Platform is made in Sweden from powder-coated aluminium, with details made of anodised hardened carbon steel and aluminium, and high-friction rubber. This model has a CE-marking Certificate as gym equipment for sport or leisure purposes and not medical devices. They comply with applicable regulations and 2001/95/EC General Product Safety Directive. The kBox4 Lite can simultaneously hold four Flywheels of up to 0.050 kgm² each, with the maximum inertia level being 0.200 kgm².

Flywheel training also offers safe and easy eccentric overload offering the user higher gains in muscle mass and strength.

A full range of attachments, harnesses and flywheels are available to customise it to your requirements.

The Kinetic Box, kBox4, is built on proven and reliable technology and a perfect tool in strength and rehabilitation for upper, lower body and core. kBox4 is used in gym, small group PT, traditional PT, by athletes in high performance sports and in clinics with patients.

There is no upper limit in how much kinetic energy you can produce, in the flywheel motion. This means that you can always use a higher force and accelerate the flywheel more. Resistance is variable in that if you pull less the flywheel will resist less. Therefore, the kBox4 is suitable for both resistance training and rehabilitation.

With FWEDs, every repetition is maximal, with both a higher force early in the set and lower in the end, making the exercise much more efficient. This is why flywheel training gives a hypertrophic response earlier in the training regimen than traditional weights.

You can also attach any handle or grip and do many upper body pulling and pushing exercises for arms, shoulders, upper and lower back.
