The dumbbell concentration curl is an effective isolation exercise for building muscle and strength in the bicep and brachialis muscles of the upper arm. Now, this is one of the most popular exercises and for good reason… it works really well for isolating the biceps and allowing for a deep contraction in the muscle.
But since it’s not a compound exercise like the barbell curl, it’s best to use light to moderate weight in order to perform the reps with a full range of motion. It’s also a great exercise for anyone at any level of training. So, make sure you try the concentration curl in combination with your other bicep exercise for maximum growth potential.
