Previous position

Bring your Left leg around in an anti-clockwise direction finishing in Front Stance (Zenkutsu Dachi) with Gedan Barai (Lower Block) 

Feet Position on Diagram Facing Screen

 

Look to your Right observing the next attack from that direction
Bring your Left foot  in a diagonal direction towards your Right foot.  Carry it on past your Right foot in the same diagonal angle so when you turn  towards the attack you finish in a wide front stance

Bring your Left hand up to your Right shoulder and stretch your Right hand in the direction you will be finishing the block ( low and to your left)
As you finish the turn,  push your Right arm and hip forward, keeping your Left arm at your shoulder until just before your feet land in the correct position 
Make sure you do not step in a straight line as this will make your stance very narrow - step out to the 7.30 clock position

As your Left foot touches the finish position, bring your Left hand quickly from your shoulder to finish about 6 inches above your knee.  At the same time bring your Right hand quickly back to your waist - palm facing upward
Make sure your front leg is bent with your knee over your toes, and your back leg is straight and locked
Breathe out completely and tense all your body muscles for a brief moment on the completion of the move
