If you want to maximize biceps activation on the dumbbell curl, you’d want to avoid excessive shoulder involvement. However, most people tend to move their elbows forward as they curl, shifting some of the tension to their shoulders. A trick to avoid this problem is to perform dumbbell curls with your upper arm resting on some sort of support, such as on the preacher curl bench or on the lat pulldown machine.
