Primary Muscles Worked:  Anterior Deltoid (front part of the shoulder).

1.    Start Position:  Stand with back straight, knees bent slightly and feet about hip width apart.  Chest lifted, abs contracted and hands in front of your thighs.
2.    Execution:  Keeping your elbows slightly bent throughout the movement.  Exhale and raise your arms from thigh level to chest level.  
3.    Pause at the top of the movement.
4.    Inhale and slowly lower your arms back to the start position.
5.    Avoid this exercise if you have any shoulder problems or feel any pain in the shoulder (or anywhere else).

Trainer Tips:
•    Proper form, posture and correct breathing is very important – not only to isolate the targeted muscle group, but also to prevent injury.
•    Making the mind/muscle connection will insure that you get the most out of the exercise.
•    Keep your abs contracted and your upper body completely still during the movement.
•    Avoid slinging the weights up.  If you are slinging the weight, it’s too heavy.
•    In plain terms, this exercise works the major muscles of the shoulders.
