There are two different levels that the program can be completed at, depending on where you are at with your lower back/ work situation and how quickly you would like to see changes.
Are you a Chair Bear or a Chair Grylls?
Chair Bears have a job that involves a fair amount of sitting, and feel stiff at the end of the day. Chair Bears want to prevent any injury from happening.
Chair Grylls spend most of their work week sitting and have a lower back specific injury (eg. Sciatic pain) that is starting to affect the rest of their life, including their sleep and is starting to drive them a bit crazy.
