I believe it. As a tough old broad, I recognize and respect another one. I’m 82, at the gym every day, Run a mile on the treadmill, do 15 - 20 minutes of weights. If Ruthie has a trainer who’s been pushing her to do her best, then this is well within reason.
There are many reasons to snipe at Ruthie, but this is not one of them.
Did you see her hobble into the room at Kavanaughs swearing in ?
I doubt she's been anywhere near a treadmill or weights in ages. Sorry, it all smells like BS to me.
