# Exercise Counter

After matching placement requirements you can start counting repetitions

PoseTracker accurately analyzes the user's motion and posture, estimating a percentage of progression for each exercise. If the user reaches *100%*, the counter increases. The difficulty level, which is an optional parameter, influences the standard (*100% above*) the user must achieve to increment the counter.

Data composition for `type: 'counter'`

```
{
  type: 'counter',
  current_count: The current exercise count. 
                 It can represent X repetition or X second holding a posture.
}
```

Possible values : 

```
{
  type: 'posture',
  current_count: 0...10000 (an interger)
}
```
