Lift: Raise a dumbbell overhead with one arm, pointing your elbow upwards and forwards. Start with your arm almost straight, just slightly bent. Now, keeping the upper arm straight, lower the forearm to 90 degrees. From this position extend at the elbow again until just before full extension. Lower slowly and under control. Do not allow the elbow to flare out to the side when performing this movement.
Repetitions: Perform all prescribed reps on one side, then on the other. This counts as one set.
Caution: Be careful with the weight overhead - make sure you can safely handle the weight and do not push failure.
