Clean and jerk
Single arm
### Single arm

A single arm is used instead of two. The weight lifted is usually a dumbbell or kettlebell. A barbell can also be used. The movement is broadly similar to the two armed clean and jerk, although there are various changes to the range of movement and posture. As a form of unilateral exercise, a single arm clean and jerk can be beneficial for core strength as the lifter has to work to stabilise the off\-centred weight. It can also help to reduce an excessive strength imbalance which has developed between the different sides of the body. For example, in a two armed clean and jerk, there may be a muscle imbalance meaning that the right arm is performing an excessively large amount of the work and the left arm an excessively small amount. By using the single arm style and alternating between each arm, it can be ensured that each arm is performing the same amount of work.
