VARIO lets users replicate their natural walking or running motion, including different stride lengths, but without impact on the joints.

It also offers the choice of working the whole body by moving the machine's handles, or keeping them static and using just the lower body.

VARIO allows individuals to work within their natural stride and is seen as a logical progression for those who use a cross-trainer, as well as for aspiring runners who currently walk on a treadmill.

Its impact-free element also benefits the deconditioned, elderly and injured, providing an alternative way to train.

As VARIO is built around natural stride length, an individual should start their workout using a stride length that feels comfortable. They can then work up to more challenging goals - including more strides per minute, building levels of resistance, integrating the upper body or increasing stride length - as they grow in endurance and confidence.

Added extras include heart-rate training or pre-defined programmes can be used as motivational tools to keep users engaged - for example, using different stride lengths to change the pace during interval training.
