The number one, most important thing in or out of powerlifting is this...If what you are doing is working and you are happy with the results, keep doing what you are doing.

There is no question that the wider grip feels better. I am a wide guy so the torque on my elbows is not pleasant with an inside grip. There is no question for me that I am stronger from that position. That said, I have been told the opposite is true for other guys who are very good curlers. If you are curling your body weight, I would never listen to someone who said you are doing it "wrong".

As I stated earlier, I think one of the most important areas to train, and train hard, is the front delts. When I curl heavy weight in comp. I try and drive my elbows up. This is a front delt movement.

One exercise I do religiously on shoulder day is seated, reversed grip (palms inward)front overhead press on a Smith Machine. I go as heavy as I can stand it for sets of 6.
