I finally made it back to the gym. As I came by bike I skipped the cardio warm up, though I might need to reconsider this for next time, at least do some jumping jacks.
The workout went ok even though I could feel my back still a bit. One exercise I had to skip because the dude there was just not moving on and I was not feeling social enough to ask him to share, but I am okay with that.
I did a bit of standing on one leg with various movements as recommended by my physio therapist to help with the imbalance that is a cause for my back pain. I keep forgetting to balance when brushing my teeth which was the recommendation.
