Human Factors
I was doing my first solo for my CFI training so I was alone in the aircraft in the right seat. I was performing engine start up procedures and had to lean over to the complete left side of the flight deck to crank the ignition switch. As I was leaned over the engine started and my feet slipped off the brake pedals. The plane moved forward and as soon as I could react I moved the throttle to idle and my feet back to the brakes. I then taxied back into the parking spot; shut down the aircraft; and canceled the flight.
SR20 pilot reported momentary loss of control following engine start from the right seat.
