I walk everyday for my exercise, but I do WATP. For me, its more then just a walk because she incorporates other moves in there. But I think adding your weights will definently help. I don't really know what else you could add, except for maybe do some interval training. Like jog for 30 seconds then walk for 2 minutes. Or something like that! Anyways, good job for 3 miles that's awesome!
