Oh no! Lumbago!

Hello,
I have lumbago. So I had to take a rest and stop the hybrid musculation program since Sunday, because as soon as I move, an intense pain almost makes me jump… Even though I told the coach not to strain my back, some exercice are impossible…
The coach told me on Sunday (and it will be like these following days too, I work out four times a week) that I didn’t record a session.
How is it now? Does the program pick up where I left off or do I “lose” the training days? I mean, the programme will stops, as the coach counted the days I did not trained?
I just do some stretching, and use some cremes and a warm belt. That all I can do…
Thank you for your answers. Best wishes.

The coach days will be moved forward until you start one of them.
No worries nothing get lost.

It’s like hitting the “Pause”-Button. Sessions just keep moving to the next day until you restart.

Thank you. It will take time as I really have pain.
