Can anyone recommend arm exercises to tone the upper arm? I've never done any before but need to as my arms are untoned and need attention 
I'm a size 8/10- not overweight but since I turned 35 (2 yrs ago) there's been a definite decline in a lot of areas and my upper arms are one of them. I want to buy dumbbells but don't know what weight to buy! Help needed.... thank you!
