This movement is only possible with a cable which is attached at the ground level.
If there is no access to this piece of equipment, please use a dumbbell.
In a standing position, knees slightly bent; grasp the handle to the cable with your
hand which is opposite to the handle's origin. Place the other hand on the the
machine for balance or on your hip.
Carefully, with your elbow locked at a slight angle, lift in an arc with your arm
straight to your side. Once your hand, elbow and shoulder are in line, pause for a
second.
Next, lower the weight back to the starting position.
Tips
This is an excellent movement for isolating the side deltoids. Once again, DO NOT
swing the weight up It is important to note that since you are using a cable, there
is constant tension on the muscle.. so perform the exercise slowly.
