I mentioned this in another thread and agree its best to stay leaner as you get older. I'm in my 50's and feel better leaner and still look full.
Ronnie was enormous for a long time so I would expect him to have some laxity to his skin. Dave Palumbo's arms seem to have that same stretched look
Not that I could ever compare myself to Ronnie, but I decided to get lean awhile back. Clearly, my time has passed a long time ago with regards to being a stage worthy contestant. I hope I didn't wait too long. My skin looks slightly loose to me in some areas, especially my abs. This is normal for men or worse for women of my age. I like to believe that a lifelong dedication to being fit and healthy can still pay off. There is no way I can keep up with someone in their prime years. I gave that up quite awhile back.
I still looked pretty decent when I was in my 50's. Each decade takes it toll though.
Seems like a lot of folks want Coleman to look like he did when he was much younger. If once is realistic, they'd realize this is not possible. You can only hope to look your best for your age and whatever card genetics dealt you. Anything else is futile.
