How do I perform a turning step-up, balance to overhead press with 2 arms?

Start

1.  Stand on one side of a box with your feet pointed straight ahead placed a little wider than hips distance apart.

2.  Hold dumbbells, shoulder heigh with palms facing forward. 

Movement

3.  Engage your core muscles by bracing abs, then turning 90 degrees pull yourslef up onto the box through the heel squeezing gluteals (butt) of the lead leg standing up straight.

4.  Balance on the lead leg while you bend your opposite leg at the hip first and then knee. 

5.  While balancing on the lead leg, press dumbells overhead just in front of face so you can see the weights. (This prevents reaching behind head with added resistance...which may cause unnecessary shoulder joint stress)

6.  Return the dumbbells to your chest and step off the box, back to the starting position.
