What is it with you an making assumptions? 1) I said I'm working been working on getting fitter and was thinking about getting weights to work on my arms a bit, so automatically you assume I'm only gonna do work on my arms? Never mind the fact dumbbells can do shoulders, chest, back and arms if you utilise them correctly. Thats the most stupid assumption ever nothing implied ONLY arms, all that was implied was getting dumbbells with a view to including arms in what I've already done. 2) You don't have to want "serious muscle" to lift weights, you can lift weights just to get some muscle definition and improve general fitness to do with strength etc. 3) I said my ARMS were skin and bone, not the entirety of me 4) I never said I wasn't doing cardio you again assumed this. It's pretty pathetic that I ask for one aspect of advice which for the most part I've got helpful responses with but someone has to ruin it by making stupid assumptions that can only be made if you ignore key words in my posts and its so closed minded they don't comprehend not everyone who lifts weights wants to get "serious muscles" or does.
