U are missing the point. If u want until your back is out it's far too late. It literally took me 5-10 minutes to get onto the floor to do a half assed version of some of these exercises.
The point is to help mobility and be stretching daily to avoid injury.
Sorry if I implied this is a good routine to do once out of commission. U will be lucky do half of them......if u can get on the floor lol.
