- 1. Sit down on a flat bench with legs positioned shoulder width apart, knees bent and feet flat on the floor. At this stage of the exercise the dumbbell should be placed on the floor, between your legs.
- 2. With whichever arm you choose to perform with first, firmly grip the dumbbell whilst keeping the previously stated body position. With the arm that isn’t being used or the ‘resting arm’, place it on the inner thigh of the leg. For example, if you are training the right bicep, the left arm will be resting and placed on the inner thigh of the left leg.
- 3. As you exhale your breath, elevate the dumbbell in a curling movement until it has reached a point of full contraction. Realistically, the dumbbell should reach to about shoulder height.
- 4. Once this point is reached, pause for a brief second, squeeze and place considerate tension on the bicep. Remember, ‘concentrate’ on that mind to muscle connection.
- 5. As you finish this contraction, breathe in and slowly release the dumbbell down back to the starting position. The rest of your body should be staying in the same position throughout without any momentum being used.
- 6. Once the required number of repetitions have been performed with one arm, repeat on the resting arm with the same applied technique and form throughout.

Mistakes commonly made in dumbbell concentration curls
When performing the dumbbell concentration curl your wrists should always be in a neutral position, not bent up or down. If you find that you cannot maintain a neutral position throughout, this means that the weights are too heavy.
You should also focus on good form rather than executing the rep quickly, at least when starting out. You should lift slowly and smoothly so that you feel the burn.
You should not use your momentum to lift the weights as this actually reduces the effectiveness of the exercise. Quickly moving the weights allows momentum to reduce the tension within the muscles, especially at the top of the lift which reduces how much your muscles end up working in the exercise.
Your elbows should not move during the dumbbell concentration curl as they should be close to the side of your body at all times.
Going Too Far Down
When performing the dumbbell concentration curl do not pull the dumbbell so far back that the forearm moves past a vertical position.
Safety when performing dumbbell concentration curls
This exercise is recommended for most people. Although if you have any arm injury or experience any pain during the motion, do not continue and stop the exercise. Although you should still talk to your doctor or physical therapist about if concentration curls are suitable for you.
When performing concentration curls you can expect to feel fatigue and possibly burning in your biceps after a few reps, and this is to get your muscles to get stronger and grow. However, do not force extra repetitions once you are unable to perform the concentration curls with good form. You should then take a rest before doing the next set.
Also, do not lift a heavy weight to begin with, don’t rush to get to heavier weights before you’re strong enough to do it with ease. Using a weight which is to heavy for you can result in Injury to the elbow or wrist, and that will affect your entire workout routine.
