Concentration Curls for Biceps: Exercise Description of Concentration Curls

Concentration curls are a great exercise for stimulating the muscle fibers on the peak of the biceps. What I love about concentration curls is the fact that if performed properly, you can fully isolate the biceps and maximize biceps stimulation. In addition, you can use this exercise for fixing symmetry issues (such as one arm being bigger than the other one), and in addition, you can self spot yourself as well by using the other hand to help you squeeze out a few more reps.
Difficulty: Average
Time Required: 30-40 seconds depending on amount of repetitions performed and setup time.

Here's How:

  1. Sit down at the edge of a flat bench that has a dumbbell right in front of it.
  2. Use the right arm to pick it up the dumbbell and place the back of that upper arm on top of your inner right thigh (around three and a half inches away from the front of the knee). Rotate the palm of the hand until it is facing forward away from your thigh. Your arm should be extended at arms length and the dumbbell should be above the floor. This will be your starting position.
  3. 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. Squeeze the biceps and hold the contracted position for a second.
  4. Slowly begin to bring the dumbbells back to the starting position as your breathe in. Avoid swinging motions at any time.
  5. Repeat for the recommended amount of repetitions. Then repeat the movement with the left arm.

Tips:

  1. This exercise can be performed standing with the torso bent forward and the arm in front of you. In this case, no leg support is used for the back of your arm so you will need to make extra effort to ensure no movement of the upper arm. This is a more challenging version of the exercise and is not recommended for people with lower back issues.
