No, I haven't gained a lot of weight
I'm carrying a stack of heavy books, balanced on my head.
They're re-carpeting the office where I work, so I've been working from home for a week. I've been trying not to work all day curled in my living room easy chair, and yet I still find myself with a stiff neck this morning. I think my neck muscles are weak.
So I've loaded a tray with a pile of heavy books, and balance it on my head while doing various household tasks. Not terribly convenient, but it's bound to tone those neck muscles. I hope.
I will say, it forces me to improvise. Not easy to stand on the scale and read it, while balancing a tray, so I used an available camera.
