You can perform the concentration curl while sitting or standing. Practice with a light weight first so you can master the movement.
Positioning
Remember to curl the weight with your arm angled in toward your body. This will ensure that you're doing the motion correctly, following the direction towards your shoulders instead of your chest.
No leaning
Rock back and forth or move your leg to help raise the weight.
::Dumbbell overhead extension ::
Correct form
Always keep elbows pointing up above you during the entire movement to create a full range motion for the triceps.
Muscle imbalance
Make sure to get an equal grip for both hands with this exercise. If not, you might end up directing the force of the dumbbell resistance to one arm more than the other.
