I started Penny's Pilates class more than five years ago, in my mid 60's, hoping to remain mobile, fit and strong into my old age, unlike my mother, who by my age had two knee replacements and was very fragile. I am now into my 70's and full of energy and optimism about the future. I love Penny's classes and we all emerge beaming from ear to ear and bodies buzzing. Can't recommend enough!
