While using IGH hub it's good to learn pedal repositioning technique different from freewheel hub.
You may observed that when bike is pushed backwards, the pedals also go backwards. Of course, at junction there is not enough distance to go back enough to lift your favourite pedal to position convenient for start. But you really need centimetres-long distance to adjust your pedal as needed, taking advantage of engagement mechanism inside.
Push back your bike a bit, that pedal lifts a bit.
Keep pedal with your feet from below, move few centimetres forward.
It can be done without coming off the bike.
But best practice is to learn positioning your pedals as you wish before you stop :)
