Ha "push down" c'mon that's just cruel
So Yeah don't pull up, pull back. On the run in up in the ready position start with a slight weight shift forward, then back(not up) till your arms are straight continue your back shift so you can build up pressure through your palms, as this happens imagine you've just fell over on ice (feet flying forwards from underneath you)
DO NOT LET YOUR ARMS BEND UNTIL YOU WANT THE FRONT WHEEL TO RETURN TO EARTH.
Practice all this on the flat many many times (top tip put a squeaky dog toy on the floor this becomes the lip of the drop, your aiming not to squeak with your front and to squeak with your rear before or as the front touches down.
Remember back not up
