Silver Foxes

Options
Just starting a group for those of us in the Medicare years who intend to be/stay foxy till we drop. I'm 65 year old, 5'9" tall, 30 pounds overweight tomboy who loves walking, biking, hiking, kayaking, traveling, and --- oh yeah -- occasionally being told I'm looking good. Why I am posting this? Someone told me today that at my age, I can never get rid of flabby arms. Hoping to hear from some like minded silvery foxy types here who are maybe also delusional enough to believe that flabby arms and tummy bulges are not mandatory after 65.
