Default dose

3 × 6 · 8s

This is the library's default dose. Each person's programme is set after assessment, around the grade of their finding and their own conditions and limits.

Muscles involved

  • working Rectus abdominis, Abdominal obliques

Muscle colours in the animation: orange working, blue stretching, amber holding still. These muscles were measured on the 3D model.

Where it sits in a programme: Activate the weak

The third phase is activation: strengthening a muscle that has become weak or underused, with controlled movement and light load, so it can carry its share of holding the body up.

Which postural findings it is prescribed for

Take care
