Fast pace walking or jogging

[Shneebz]

I would like to know what some would prefer a fast pace walk or a jog?

Is jogging more effective or does it really matter which

I like to mix it up. I call it walk/jog and it's something i do around the park. because i have bad knees, i jog on the grass and walk on the sidewalk. it keeps up heart rate and varies intensity which is a good thing when it comes to burning fat when doing it for longer than 20 minutes
