On the bright side, I like doing squats with a loaded barbell, and a bunch of things I'd been worrying and obsessing over abated with my physical misery.
So. No gym today! Not even cardio. It is an official Recovery Day.
I am back to thinking I need some trainer sessions. Definitely, I will further adapt what I'm doing and how much I'm lifting and for how long at my next session. Which might well be Monday.
I must remember I am not in my twenties or even thirties. Two days recovery after serious lifting seems to be working better for me than one day.
