You are never too old to begin your Pilates practice. If you are 60 or older and are active, you are ready to start. If you have any pre-existing conditions or have not been active for a while, consult with your doctor before beginning any new exercise. It's never too late to learn to use your body in a smarter, more efficient fashion with Pilates. And the loss of flexibility that we associate with aging can be reversed. Take your time. Pilates requires focus, attention, deliberate movement, slowing down, and staying aware of your body. There is always a way to modify and exercise. Err on the side of caution, not because you "can't" do something, but because you want to do it well. You will feel the positive impact of Pilates by merely practicing it regularly.
