Leslie's 2009 workout,
Walk Off Even More Weight, came with a 2-lb weighted belt. This workout was one of the sets sold only at Target. (You can find it at a high price on Amazon. I'm not sure if it still comes with the belt.)
I like the workout and I really like the belt. I use it with many workouts, both cardio and strength.
My Leslie belt is a bit worn. I own another, adjustable belt that goes up to (I think) 10-lbs for if I'm feeling frisky.
