Common mistakes In Concentration And Preacher Curls

Concentration Curl Mistakes

The elbow is getting overextended and chances of injuries and joint strain are increased because the weight is released too quickly. You must lift and lower the dumbbell slowly. 

The activation of muscles happens when you are at the top of the life and your hand is closest to your shoulder. If you do not move your hand through a full range of motion, your muscles will not get activated the way they should. 

You fail to maintain constant tension by hanging the weight at the bottom of each repetition. You may feel tempted to relax between each repetition, which you must consciously avoid. 

Preacher Curl Mistakes

Failing to move through the full range of motion may not give you desired results. The biceps get activated the most when it is in the stretched position. So, you must fully lower the weight for each repetition so that muscles get stimulated. 

More extending of elbows may happen in Preacher curl because you get the false sense of security due to the preacher pad. Overextending of the elbows increases the chances of injuries and strains. 

Your triceps may lose contact with the preacher pad, which must be avoided. If you move your arm, the emphasis will be on the shoulder and not on the biceps. So, you may not get the optimum result of doing Preacher curl.
