The kBox4 Pro is set apart by its market leading maximum inertia, built-in kMeter II feedback system and larger surface area, loved by strength and conditioning coaches as well as physiotherapists and top level personal trainers.
The kBox4 Pro Platform is made in Sweden from powder-coated aluminium, with details made of anodized hardened carbon steel and aluminium, and high-friction rubber. This model has a CE-marking Certificate as a Medical Device. The kBox4 Pro can simultaneously hold four Flywheels of up to 0.070 kgm² each, with the maximum inertia level being 0.280 kgm².
With the kBox and kPulley, instead of a fixed load determined by gravity when lifting weights, you work against the variable inertia of heavy steel flywheels determined by the effort and energy you unleash into the device.
These training devices are truly versatile and serve multiple purposes, allowing you to engage your upper body, core and lower body with a wide variety of exercises.
The kBox is renowned for its genial application of eccentric overload in regular training as well as its variable resistance, both backed by growing scientific support.
