Is walking exercise?

Tiffany

So my hubby and I have had a friendly disagreement about this for some time - I believe walking is great exercise, especially when pregnant. Obviously I understand it’s also important to push yourself with something more strenuous when you are able to, but I have suffered from Pelvic Girdle Pain my last two pregnancies so I am happy to be able to go for walks and do prenatal yoga without too much pain, everything else is excruciating. My husband is in the military and must keep up his physical fitness but he really doesn’t believe walking or even yoga should be considered exercise, as it’s too gentle to do any good. I’d just like to enlighten him a bit...haha, so if you have any good articles or such feel free to post them here!
