Bicep dumbbell curls are the best exercise for sculpting sexy arms but to get great results it's best to do a non-traditional type of bicep curl. Traditional bicep curls isolate the muscle but they don't burn many calories or fat so chances are you'll never get lean enough to see those sexy bicep curves. If you want firm arms then try bicep curls that also work the legs, core, and shoulders like the ones below.
