DavenportThe take-off: Kevin straightens his legs and springs using the tail of the board to pop up into the airPhotograph: Allen G. DavenportThe manoeuvre: a basic straight air jump. Knees bent, arms centred, board flat. Your back should be straight Photograph: Allen G. DavenportThe body is compressed for amplitude and balance. Keep your shoulders orientated to the slope. Once in the air, pick your knees up again Photograph: Allen G. DavenportThe landing: the legs are extended to absorb the shock - flat board for landing again.
