I have quasi recovered from a HORRENDOUS hellish two days of back agony. I am usually super fit - Caroline Girvan many days a week and yoga days for relaxation in between. I don't think regular Epic caused it (maybe I overdid a HIIT day while recovering from covid but those are only weekly), I have been properly taught about weights from years at the gym prior to home workouts and not lifting at my max.
The breathe in/straighten to breath out/extend/twist type yoga movements probably broke the camel's back (or mine anyway!) as I felt it instantly.
So in terms of dodgy backs, am I now prone to this forever (my friend who has back issues says to 'never lift anything heavy ever again'). My instinct tells me to wait until Christmas is out of the way and build it up slowly but only if it will never, EVER happen again!!!! WWYD?
