The Technology behind the Grucox Eccentric Trainer

The Grucox Eccentric trainer employs a state of the art feedback system, which allows for accurate regulation of speed and torque as well as the precise measurement of the torque and power applied by each leg – giving the user a unique training experience.

In essence, the Grucox Eccentric Trainer is an interactive leg training machine, which allows the user to combine eccentric and concentric exercises, while monitoring their performance data. In so doing this allows the user to optimize a training routine in order to achieve maximum strength gains in the shortest period of time.

The Drive Train System employs an advanced electric motor system with a robust speed reduction assembly. Apart from regulating the torque and speed, the system also has advanced safety features – minimizing the risk of injury or over straining.

Training management is done via an intuitive touch screen interface and unique operating software. In another first for indoor trainers, the Grucox Eccentric Trainer displays real-time torque and power output for each leg individually, enabling comparative strength assessment and progress tracking.

The Grucox Eccentric Trainer comes pre-loaded with a host of training and rehabilitation programs as well as a complete set of muscle function tests:

  • Rehabilitation – Bilateral
  • Rehabilitation – Left Leg
  • Rehabilitation – Right Leg
  • VO2 Max Protocol 1
  • VO2 Max Protocol 2
  • VO2 Max Protocol 3
  • Proprioception Protocol
  • CPM Protocol
  • Dynamic Strength Test
  • Static Strength Test
  • VO2 Max Test
  • FTP Test (FunctionalThreshold Power)
  • SpinShaper
  • Weigh Yourself
  • Custom Program

Patient Management and History File

We have gone one step further with patient management. Each training session is recorded in our central data warehouse and can be accessed securely via your own private profile on

A patient has the ability to create a unique profile on any Grucox Eccentric Trainer and have all their training sessions recorded in one place. This allows full data portability and means that you can review the entire history file of a patient. With our sophisticated patient/practitioner management software you can view all your patient’s training files, and even assign additional management/review roles to other members in your healthcare practice.

The other major advantage of our system is the ability to review a patient’straining performance online and send them a private message with an assessment and follow up recommendations. All that is required is a computer with Internet access – no fancy software to install.

Through sophisticated encryption technology the privacy and confidentiality of all patient information is guaranteed.
