Exercises for long head of biceps
I've just read an article on this site:
[url]http://www.bodybuilding.com/fun/the-science-of-arm-training-arm-workouts.html[/url]
In it, the author states the following:
"If you want to focus on the long head of your biceps, extend the shoulder or get your elbow slightly behind your body. This is most-easily done using incline curl variants."
I've noticed that part of my biceps is lacking compared to the short head (the peak is good, width is poor).
I'm not keen on incline curls as it requires a bench - gym is busy always, and lacks equipment so I try to train by using as little equipment as possible.
So
1: What does the author mean by "extend the shoulder"?
2: What biceps excercise(s) achieve this?
