Not sure if this was asnwered anywhere before, but it is bugging me. If I play something like DDR, which only uses the legs, will I lose fat elsewhere on my body? Like my arms or stomach, etc. Or will I only lose it on my lower body?

You can't spot reduce so the opposite is to say that fat you burn is determined by your body, not where you work out.

Okay, just wanted to check. I can do DDR pertty good, since it only uses the legs, but I can't do much actual aerobics yet. I don't have the stamina to. So I just wanted to make sure I wouldn't only lose in my lower body if I did DDR every day.

Nope, you should lose around your whole body. Maybe you can hold some light weights while playing?

I have some that velcro on. They have little pockets that hold little tubes full of sand, so you can adjust. I'll try those, thanks. I forgot about them until I saw your post.
