Optimal Amount of Exercise to Slow Aging
As a 54-year-old woman in good health, I am trying hard to stay that way. I want to stay mobile and active well into my later years. My weight is normal, I eat as conscientiously as possible, and I consider my health excellent.
The one thing, however, that I'm just not sure of is how much exercise do I really need? Every morning I do a very brisk 20-25 minute walk with my Jack Russell mix (I try to match his pace!) which I enjoy very much. I also do modified pushups (1 set of 20 followed quickly by a set of 10) plus 20-second planks every other day.
I used to also do daily aerobic and every other day weights using a video "step" program but always ended up with some kind of injury or pain that made me have to stop altogether for a few days.
I'm not an athlete, although I do alpine ski in the winter and I am at a desk all day long at my work.
Can you give me any advice on how best to maintain my current fitness and weight and add to my long-term health?
