I have a problem with shoulder shrugs, that is i'm confused about what weight i should be using and what technique.
I workout at home and therefore dont really have anyone around me to compare technique and possibly get a reference for what weight seems right for growth.
When i started doing shrugs, it soon came apparent that i could load the bar up with any weight i liked! Say 100Kg + (220Lbs) Didn't seem to matter, i could still pull my traps right up. I use a Barbell and not Dumbells because i can get more weight on the Barbell.
I recently visited a website that suggested i do behind back shrugs as it helps to avoid 'cheating'. I have to say that behind back does seem to 'hit the spot' much better.
BUT! I can still load the bar as heavy as i like.
Does anyone have any tips they want to share on their technique and give an example of the weight they are using? Does anyone know if the behind back technique will result in an imbalance in my traps? I'm 6ft 2in and have quite a long neck and would like big upper traps to avoid looking like a Giraffe!

Thanks in advace,
