Sara it is a particular spot. It's on the back but to the sides. It could probably be described as a pressure point. The belt does stick all over but I don't get the spots anywhere else.
Angelina I did gain some weight that I'm now losing but the belt is adjustable so having it on the largest setting is "comfortable" to wear. I just don't want to be on the largest setting. I've already lost 7 lbs. I'm hoping to lose 5 more.
