One-Arm Triceps Extension

Performance

1. To begin, stand up with a dumbbell held in one hand. Your feet should be about shoulder width           apart from each other. Now fully extend the arm with the dumbbell over your head.

2.  This will be your starting position.

3. Slowly lower the dumbbell behind your head as you hold the upper arm stationary. Inhale as you 
    perform this movement and pause when your triceps are fully stretched.

4. Go back to the starting position by using the triceps to raise the dumbbell. Breathe out as you 
    perform this step.

5.  Repeat for the recommended amount of repetitions and switch arms.
