I walk 4.5 miles 6 days a week on most weeks. About a month ago I started to put little jogs in my walking. I was only able to get in a couple at first, and they are short, usually not even 1/10 of a mile-each day I would do 1 more. I was able to get up to 22 jogs, but now, since it's so hot, I have cut that back to almost half-don't feel like dying out there!
I don't like jogging, only did it so it would put a small boost in my routine that my body seemed to have gotten so use to doing. It's not good for my knees either. I love walking! I have my walkman with some great hip-hop music, a fanny pack with my water bottle and a device I use called the Powerbelt that has weights on it for my arms.
I'd say stick to walking, at least for now. You can try jogging in the future.
And yes, you will have stronger lungs and a stronger heart by losing the weight AND walking.
GOOD LUCK!!!
