The biceps are comprised of two heads.
The short head is the inner side of your biceps.
The long head is the outer side of your biceps.
Wide Grip Barbell Curls
A wider than shoulder-width grip on ther barbell will place a greater emphasis on the short (inner) head of the biceps.
If you've got a decent bicep peak but your arms are lacking that overall thickness then you'll benefit from mixing some wide grip curls into your routine.
The wide grip barbell curl is best performed utilizing the widest pre-set grip on a EZ-Curl bar as your wrists will not be as stressed as if you assumed the same grip on a straight olympic barbell, if you encounter any elbow pain with the wider grip I recommend lowering the weight and slowly building your way back up.
Hit Your Regular Barbell Curls Too!
The regular barbell bicep curl utilizes a shoulder-width grip.
This grip placement allows an even emphasis on both the short and long head of the biceps.
The shoulder-width grip is without a doubt the most comfortable grip to use as there's no additional pressure or stress on the wrists which many guys find to be a sticking point as they progress with the barbell curl.
The shoulder-width barbell curl is best performed with an olympic barbell.
