Week 4: Your First Full Practice Week 4: Your First Full Practice
Centr Team
02 Nov 2026
By week four the sessions stop feeling like a series of exercises and start feeling like a practice. Transitions tighten, and the jumpboard arrives.
What Is New
- Full-body flow and transitions: Moving between blocks becomes part of the work.
- The jumpboard: Introduced this week, and back in weeks five and six.
- Upper body and obliques: Rotation under load.
About the Jumpboard
The jumpboard clips to the end of the Reformer and turns the carriage into a horizontal jump. It is cardio, but lying down, with your spine supported and your joints taking a fraction of the load they would standing up.
Your first jumpboard session is a teaching session. Expect to spend time on the landing rather than the jump. Quiet, rolling landings through the whole foot are the thing to aim for, and they are what keeps the work comfortable as the intervals get longer.
You will need the jumpboard from this week onward. It ships with your Reformer, so have it ready before you start.
