• What he said plus use a toestrap to hold the crank to somewhere in the frame, use your own judgement, chain stays are usually well solid. Insert your 8mm Allen, then use a handlebar or a seatpost as breaker bar and push hard counter clockwise.
    Make sure your extracting nut is back in place with all threads well engaged, and put it in the floor. SRAM recommends a massive torque of 50Nm, sometimes I even struggle to remove my own cranks.

    This sounds like a recipe for disaster and totally pointless.

    NDS bolt going anti clockwise is like pedalling so you can use the drivetrain/a bit of rear brake to push against.

  • It's not. Usually you'll have to hold the pedal and push the tool the other way, and that in most cases is enough. This is when everything else fails and the breaker bar is in. Is hard to hold a 175mm crank when the other way you're applying force with a 700mm lever.
