How to Biceps Concentration Curls and it’s Mechanics

Written by Dr. Neeraj Mehta, PhD · · 4 min read

Correct Dumbbell Concentration Curl Training Methods 

Dumbbell concentration curls can be performed in a variety of positions, including sitting, standing, and kneeling. 

In a steadfast stance 

Bend your knees slightly and grab the dumbbell with one hand, allowing your other arm to rest on the floor. 

Sit on a flat bench with your legs spread apart in a V and lean forward while in this position. 

Place the dumbbell in one hand, palm facing up, on the inside of your knee, if you’re standing, or just above your knee, if you’re seated. 

As you inhale, slowly bring the dumbbell toward your shoulder, keeping your torso and upper arm stationary. 

Using a wrist twist, raise your index finger towards your chest (i.e., supinate). 

One count of biceps squeezed at the top, then slowly lower the elbow to the starting position while exhaling, then repeat. 

To complete your desired sets, switch arms after completing your desired number of repetitions with one arm. 

In a seated posture. 

Place your feet firmly on the floor while you sit on a gym bench. 

Take hold of a weighted dumbbell. 

To begin, stand with your feet hip-width apart and your upper arm resting on the inner thigh of the leg to your left or right, depending on your preference. 

In order to get a better workout, the dumbbell curl is done with this support in place. 

If you’re looking for a more advanced twist on this variation, you can let your arm fall without using your inner thigh for support. 

Focus on maintaining a straight back and a stable head position while bracing the abdomen. 

Inhale, then exhale, then exhale. 

Squeeze at the end of the movement. 

Repeat 

Keep in mind that you should exhale during exertion and inhale during recovery. 

Performing Dumbbell Concentration Curls: Some Proven Techniques 

Incorporating more muscle fibers into each repetition will help your muscles grow in size and strength, making them stronger and more pliable. 

Form and control should be practiced. 

If you’ve never done this exercise before, or any other lift, start with a light weight and work your way up until you’ve completed the full range of motion with proper extension and contraction. 

Wrist-twisting is a simple motion. 

In order to develop the biceps brachii’s long and short heads, you need to twist your wrist (turn your little finger upward). 

Keep your elbows loose at all times. 

Avoid locking your elbows as you lower your biceps into the position. 

Avoid raising your elbow. 

Keeping your elbow against your thigh will keep you from swinging the dumbbell instead of lifting it, which will help you keep your balance. 

Squeeze the apex. 

Feel the burn as you squeeze the top. 

Take it slow. 

Keep the bicep in tension as you lower to the starting position.. 

Dumbbell Concentration Curls Mistakes People Make Often 

Improperly executed exercises are often referred to as “cheating,” and this results in muscle growth being hindered, not achieving the desired results. 

You’re doing it too quickly. 

Slow and controlled movement is best. 

You’re overdoing it with the weight. 

Trying to lift too much resistance or weight is a common blunder for many lifters. 

Keep in mind that proper form and full range of motion can only be achieved with the correct weight. 

Do not use a dumbbell swing to lift. 

Your elbow is not resting on your leg. 

Lifting the dumbbell will be more difficult if your elbow is not firmly pressed against your leg. 

Elbows clenched. 

At the bottom of this movement, locking the elbows takes the strain off the muscles. 

There is too much restriction on movement. 

Keep your range of motion as wide as possible. 

Squeeze your biceps and twist your wrist to ensure that the movement is completed completely.
