What is it for?

The system allows you to register your muscles’ biopotential (EMG) and monitor the activity throughout the workout

Myographic system enables you to assess and compare how different muscles get engaged in the moving pattern.


What Is Callibri Muscle Tracker?

Callibri Muscle Tracker system consists of four Bluetooth-connected Callibri sensors and software for your computer that helps you estimate and track how your body works when you exercise.

We have created a wireless system to minimize signal interference and ensure the most accurate results so you can analyze your workout process in finest details.

Here’s what you get with using Callibri Muscle Tracker for fitness:

  • real time multichannel recording of athlete’s muscle activity;
  • instant analysis of workout effectiveness;
  • visualized activity of the chosen zones in real time;
  • assessment and performance prediction;
  • analysis of individual muscle activity features based on electromyogram;
  • «movement tuning» for asymmetrical engagement.


At the presentation of Nike sneakers, an analysis of muscle tone of athletes using the Callibri Muscle Tracker was performed

How is it applied?

Callibri Muscle Tracker Myographic system is widely used in professional fitness sphere

Easy-to-use Callibri Muscle tracker system does not require any special skills or experience.



  1. EMG is recorded via wireless self-adhesive sensors placed on muscles you choose monitor;
