To achieve the two step take off  hands should start above the head with the take off foot almost directly under the top hand.

 The set up of the take off position is really important, the position of the foot at take off and where it is in relation to the top arm. If the take off foot is too close it puts too much pressure on the arm to move the pole over, if it is too far away it doesn't allow a connection at take off to be able to move the pole forward.

Don't extend grip too much but make sure of full extension at take off with a straight arm driving through the take off foot. At take off be sure to drive the top arm forward so the pole is moved to the vertical.
