Concentration Curl
The point of Concentration Curl is control through the whole range; independent dumbbell loading is how it gets there.
How to do Concentration Curl
- Sit down on a flat bench with one dumbbell in front of you between your legs. Your legs should be spread with your knees bent and feet on the floor.
- Use your right arm to pick the dumbbell up. Place the back of your right upper arm on the top of your inner right thigh. Rotate the palm of your hand until it is facing forward away from your thigh. Tip: Your arm should be extended and the dumbbell should be above the floor. This will be your starting position.
- While holding the upper arm stationary, curl the weights forward while contracting the biceps as you breathe out. Only the forearms should move. Continue the movement until your biceps are fully contracted and the dumbbells are at shoulder level. Tip: At the top of the movement make sure that the little finger of your arm is higher than your thumb. This guarantees a good contraction. Hold the contracted position for a second as you squeeze the biceps.
- Slowly begin to bring the dumbbells back to starting position as your breathe in. Caution: Avoid swinging motions at any time.
- Repeat for the recommended amount of repetitions. Then repeat the movement with the left arm.

Common Concentration Curl Mistakes
Letting the bells drift off the working path
Keep both dumbbells travelling the same line on every rep.
Letting a nearby joint take over as the set gets hard
Stop the set as soon as the working joint stops leading the movement.
Training every set to failure this early
Leave two or three reps in the tank and add sets instead.

What muscles does the Concentration Curl work?
The Concentration Curl primarily targets the biceps. It is classified as a arms exercise and is performed with dumbbells.
How many sets and reps of the Concentration Curl should I do?
For muscle growth: 3 sets of 10-12 reps with 90 seconds of rest. Size up only when both sides finish equally strong. Adjust the load rather than the rep target if form breaks down before the final rep.
Is the Concentration Curl good for beginners?
Yes. The Concentration Curl is a beginner-level movement, so it is a reasonable place to start. Keep the load light enough that you can control every rep and stop 2-3 reps short of failure while you learn the pattern.
What can I do instead of the Concentration Curl?
Try the Cable Concentration Curl, Band Alternating Biceps Curl or the Biceps Narrow Pull-ups. Each trains the biceps with a similar movement pattern, so you can swap based on the equipment you have available.
