I guess I was curious as to your source. Again, this is contrary to everything I have ever read. At one time, I was working towards a degree in health ed so I could become a teacher after I retired from my current job. Back then, swimming was the king of low impact high aerobic exercise with walking coming in a decently close second. Maybe the thinking has changed, as this stuff tends to, but then walking was considered great exercise for everyone. I am not talking about wandering around the mall but at a higher intensity.
A quick google supports what I thought but maybe there is newer research out there I am missing...
Walking as an exercise
Walking is good
... especially at the highest intensity you can handle.
And it doesn't hurt to throw in some hills and stairs too, if you're able to do that.
