This video is half leg, foot flexing, leg crossing then half leg flexing and pedal pumping while cranking from the ankle and calves.

Sat at the table Im looking over some diagrams before heading to work. I cross and uncross my legs and repeatedly point my toes.
I spot the time and realise Im running behind! I get into the car and knowing its usually hard to start, I give it lots of pumping priming before cranking it over. As time goes by my pedal pumping gets firmer and faster, so you can hear the pedal hitting the floor.
