Hi JayKay,
Gee are we going to the same wedding with the same arms? I put my hand in my sweater and my mother's arm came out!!!!
Really, I have a wedding to attend on July 6th (Matron of Honor!) and I would like my arms to look better but it's such a slow process. You are correct that push ups and dips will help. I use 8-10 pound dumbbells too and I've seen some improvement but not much. I think this is one area that takes a lot of time and effort! Someone posted how our weight/fat loss occurs and this area is the slowest.
Have a great time at the wedding.
Maureen
