Set the wall to 45 degrees and bump from the side pulls to the gastons and back for 30 seconds over 2 reps.
Focus on pushing hard with your legs/feet and staying tight throughout your entire core. It also helps to move with momentum towards the holds between each movement.
This takes practice and should be done after a good warm up or even after climbing for a while, but never at the beginning of a workout.
