Going to the gym is so much easier when there's a buddy to go with you. At the expensive gym, I had a trainer. At the cheap gym, I'd go 2-3 times a week, and one of those would be with Max. Max is out of town for 10 days.
BUT, after a month on my own, my shoulders are bigger. It FEELS weird, and a bunch of my shirts don't come down far enough in the back anymore (already hard to get tall shirts).
I didn't lose any weight, but I've bumped up my gym weights (by mass, or by repetitions) every week. I have a note on my phone that lists the setting and repetitions of each exercise, and I update that between sets. I use an HRM strap and upload workouts to MFP, then update the description with the list (Garmin and MyFitnessPal).
So, I need to suck it up and go tomorrow anyway. My back has been a bit sore, so I've tried to work around that. Bench row instead of cable/mid row; no bend/twist exercises; To compensate, I need to add planks all 4 sides, plus leg lifts for core strength.
