I am so in love with this series. I'm starting week 5 and I cannot believe the changes already. I'm also increasing some of my weights. I just bought 20 and 25 lb dumbbells. Does anyone know how to get rid of the oil smell on the ones coated with black? My 20's have the black coating and the smell is horrible. My husband makes me keep them outside. I've tried lysol and some other cleaners, but no help.
