For auto-transmissions, you don't need to press the pedal to move if you're in Reverse gear. The engine torque (?) will move you, unless you're sitting on an inhospitable incline (which should be avoided, too).
Basically, don't touch the gas pedal if you are reversing. The engine will move your vehicle naturally & pushing the accel pedal is just a waste. No one accelerates in reverse (except in the movies) for any good purpose.
