shake weight
Just like anything else, if you're consistent you CAN have results!
(It's $20+ Shipping but they sell them at Target, WalMart, even BedBath&Beyond); I've been doing it for about three weeks now and definitely feel a difference. It won't get rid of the flab but it WILL build and tone your muscles reducing the appearance of "loose skin" which is pretty-much inevitable.
I've been struggling a bit with the arm situation... but my hunnie helped put it into perspective when he said what's worse... big chubby inflated arms or much smaller but deflated??
My Shake Weight weighs 2 1/2" lbs but it's not about that... i's about the "Dynamic Inertia"
Not to mention... it's fricking hysterical when brought out at parties (just say'in)
By the by, I am 44 now, had surgery at 42, had been 250ish pounds for a good 10 years.
A before.

An after

You can see, I have nice bumflaps :} but my arms are okiedoke and my bat wings (the bra flap folds smoothed out.)
This is just a progression of sorts.

So, while not everyone cares for muscle on chicks, and I can dig it, it really has helped me not to be a human that has gone from focusing on how large I was, to how wrankly I am. :}
Good luck girlie!
