It certainly doesn't sound like much - my heavy winter boots have got to weigh at least that.
But when you are trying to lift those legs off the floor from a prone position, those extra five pounds are a lot.
The standing kicks and exercises are not as hard as the laying down ones.
The abs can certainly feel it too.
It's only been one day since I have used them, and I think I will put them on every other day for a couple of weeks.
Build up the muscles a bit before I slam them with everyday.
