The dumbbell reverse-grip concentration curl is an isolation exercise which targets the biceps brachii and brachioradialis muscles. The biceps are pretty self-explanatory for most people but for those not familiar with the brachioradialis, it’s a muscle which flexes the forearm at the elbow.
Now, any type of bicep curl with a neutral or pronated grip will hit the brachioradialis the best. But it does also get a little stimulation during regular bicep curls and back exercises as well. However, since we’re trying to isolate this muscle the focus will be on the dumbbell reverse-grip concentration curl which is effective.
