Dumbbell Concentration Curl
The dumbbell concentration curl is an essential biceps isolation exercise.
If you want to improve your arm size, strength, and appearance, the dumbbell concentration curl is for you.
Muscles Worked By The Dumbbell Concentration Curl
Primary Muscle Groups:
The dumbbell concentration curl primarily works your biceps brachii.
The bicep muscle is comprised of two “heads:” a long head and a short head. Both heads work together as a cohesive unit during lifting and pulling motions.
Secondary Muscle Groups:
The dumbbell concentration curl secondarily works your brachialis, a muscle in your biceps that lies beneath your biceps brachii.
It also activates smaller muscles in your forearms to stabilize your arm during the curling motion.
Dumbbell Concentration Curl Benefits
1. Strength And Size Gains
The concentration curl is a premier bicep exercise. Because your arm is in an anchored position, your biceps receive more tension than they do during a standard bicep curl.
As a result, this isolation exercise strengthens the biceps muscle and increases biceps hypertrophy.
Growing your biceps muscles isn’t just for show — it will improve your performance in other exercises at the gym such as the barbell row and the lat pulldown.
2. Improved Athletic Performance
The dumbbell concentration curl can also provide a major boost to your athletic performance. Any sport that involves throwing, swinging, rowing, and other similar motions depends upon strong biceps.
For that reason, doing concentration curls can help you throw farther and row longer. Simply put, the dumbbell concentration curl can give you an extra edge over your competitors.
3. Improved Aesthetics
Let’s face it — nearly everyone wants to have better looking arms. Depending on your goals, you can use the dumbbell concentration curl to develop bigger, more toned, or more defined biceps.
This exercise is simple to learn and can help you improve the appearance of your arms in no time.
How To Do The Dumbbell Concentration Curl
For this exercise, you will need one dumbbell.
a) Grab a dumbbell with an underhand grip.
b) Assume a sitting position on a bench with your feet planted firmly on the ground.
c) Place your elbow on the inside of your thigh just above your knee for support. Your arm should be straight and the dumbbell should be just above the ground.
a) Contract your bicep to curl the dumbbell upwards.
b) Squeeze your bicep hard at the top of the rep and return to the starting position.
c) Repeat for the desired number of reps and be sure to switch arms.
If you are new to the dumbbell concentration curl, choose a light weight to begin and complete 3-4 sets of 10-15 reps.
If you are more comfortable with the form, grab a pair of heavier dumbbells and stick to the 6-8 rep range for 3-4 sets.
Dumbbell Concentration Curl Mistakes
1. Completing Partial Reps
The most common concentration curl mistake is completing partial reps. Lifters either stop short of curling all the way up or they don’t return the dumbbell to the starting position.
Either way, this mistake is preventing you from maximizing the concentration curl. Remember—it is always better to lift less weight with perfect form than more weight with poor form. Feel free to reduce your weight and perform complete repetitions.
2. Using Momentum
The dumbbell concentration curl is designed to prevent people from using momentum to lift the weight up. However, some lifters still make this mistake by moving their legs and upper body to swing the dumbbell up.
Truth be told, this happens because they are trying to lift too much weight.
The fix is simple: choose a lighter weight and focus on perfecting your form. You will actually increase your gains and reduce your chances of injury!
3. Rushing The Motion
Another common mistake made during the dumbbell concentration curl is rushing the motion. In other words, people curl upwards in a controlled fashion and then let the dumbbell fall quickly to the bottom.
Not only can this be unsafe, but this mistake is stealing major gains that can be made during the eccentric portion of the exercise motion.
Instead of rushing through the motion, curl the dumbbell up and down in a slow, controlled fashion. This tempo will increase your time under tension and maximize the benefits of the dumbbell concentration curl.
Dumbbell Concentration Curl Variations
1. Standing Concentration Curl
Assume a standing position with your feet wider than shoulder width apart. Grab the kettlebell with your right hand and your palm facing away from you.
Shift your weight to your right side and place your elbow on the inside of your thigh just above your knee for support.
With this stable base, complete the concentration curl with the same form as the standard variation. Repeat and be sure to switch arms!
2. Landmine Concentration Curl
Secure the barbell in a landmine attachment, a corner, or however you can stabilize the end of one side of the bar on the ground in front of you.
Straddle the barbell so that you are nearly perpendicular to it.
Hinge at the waist and anchor your right elbow to the inside of your right thigh just above your knee. Grab the barbell with your right hand and your palm facing upwards.
Complete the landmine concentration curl with the same form as the standard variation. Repeat and be sure to switch arms!
3. Body Weight Concentration Curl
No equipment? No problem! You can still do the concentration curl without any weights.
Begin by sitting in a chair. With your right foot planted firmly on the ground, grab the back of your left leg with your right hand.
With your right elbow planted securely on the inside of your right thigh, use your leg as resistance and contract your right bicep to lift your left leg upwards.
Then, return to the starting position and repeat. Be sure to switch legs!
