# \[developer plan] Exercise Progression

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. PoseTracker will post message with this data composition :

```
{
    "type": "progression",
    "value": 10
}
```

Possible values : 

```
{
  type: 'progression',
  value: 0...100 (a percentage)
}
```
