Thanks for that great advice. now that i think about it, i dont think my m8s keep there elbows in at all when doing curls and i keep my elbows tucked right in (possibly even resting on my hips, is this ok?) and another mate does like to swing a great deal when doing curls. I look at the definition on their arms and think that i must be doing something wrong as i cant lift as much and dont have bulging muscles!
Think i'll carry on on the weight i'm doing while they shoot off ahead with heavier weights and we'll see what happens in the end - after all they do comment that they would love to have arms the size of mine so having defination cant be that great!
Cheers again..
