Barbell Curl biceps

Barbell Curl biceps
The first biceps exercise to perform is barbell biceps curlr, which will also allow you to overload those biceps with a heavy weight. Most trainees are slightly stronger when lifting a barbell versus a set of Dumbbells,so this is a great one for maximum strength development.
The single biggest mistake lifters make on this exercise is swinging the body back to assist in moving the weight up. This is cheating! Your body should remain fixed and only your biceps should be used to move the weight.
Another mistake is not keeping the elbows fixed and in at the sides. You should not let your elbows come forward when moving the weight up.
