dumbbell front raise

Is this a good exercise for swimmers? I tried it recently and was surprised how weak I was on my non-dominant (right) side, which is also the side I've had some nagging shoulder soreness up until recently. I have been ignoring my deltoids in my weight training routine up until about a month ago, to go easy on my shoulders. Recently I started doing some exercises that target the deltoids and my shoulder soreness has diminished a lot, so I plan to keep it up and maybe try more exercises.
