Primary Muscles Worked:  Biceps

1.    Start Position:  Inspect the tube for any tears or worn spots.  Stand securely on a light tube with one or both feet.  Arms fully extended at your sides, handles in each hand.  Abs contracted, chest lifted and shoulders down away from your ears.  Stand tall.
2.    Execution:  Exhale as you bend/flex your elbows, curling your hands up and toward your shoulder.  Pause at the top of the movement and contract your biceps.  Keep your wrists firm and elbows at your side.
3.    Inhale and slowly control the movement back to the start position.  
4.    Avoid this exercise if you have any elbow or shoulder problems or feel pain in the elbows or shoulders (or anywhere else).

Trainer Tips:
•    Proper form, posture and correct breathing are 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.
•    Adjust the tension of the tube as needed to add challenge while still keeping good form.
