Sounds like a bit of modelling 'on the stand' is required - or in this case, 'on the dolly'! ;) I used to do that a lot in the dolly dressing days of my youth.
At 5'3" and 213 lbs, and a lot of extra pain and lack of breath and movement, summat had to give. On top of that and the fibro, I developed gall bladder disease. Shifting the weight was easier than hauling the extra mass, so it went! So did the gall bladder. Now, except for the fibro and the RSI, I'm slimmer and fitter at 50 than I was at 30, which is a bit scary, but rather nice. I can now hop up and down the loft ladder to the fabric stash with greater alacrity, and I generally have better stamina and suppleness than before, so though there are times when the RSI bites and the fibro lays me flat for a while, on the whole I'm so much better off than I was that there is no going back - ever!
