Oh, yeah. I'm totally seeing this now. I've been trying to work out and keep some strength up, but I find myself defeated by the oddest things. Wrenching on the car, of course, so I need a bigger breaker bar and am contemplating a pneumatic wrench. Pickle jars! Now I'm jimmying the lids to loosen them up so I can open them.
I did lose two inches of chest size (under the new growth, which has added a couple inches 🙂 ).
More recently, I haven't been able to work out for two weeks from a recent surgery, and am looking at several days more before I can go running or use the elliptical. I'm dreading what my endurance will look like.
