Here's a tip.It can be a bloody, sweary strugglefest if you don't cover the chainset.
Turn the crank so it points forward of the chainrings, horizontal, then put the spanner on so it sits above the crank arm with the handle towards the back of the bike, leaving a gap of a couple of inches. You can now take hold of the spanner and the crank arm and squeeze them together with one hand. No danger of skidding off and skinning your knuckles, and as long as you always point the crank forwards the same orientation works for both sides.

mind you I can bend the 6mm one on a tight pedal - it's about 5 inches - so I'd be able to snap a 12 inch long one
As it is, I use an old ice screw to elongate the 8mm key to get sufficient leverage but with the 6mm one, it has to be clamped in a bench vice with just the end poking up and you have to remove the crank/chainset and bring the mountain to Moses as it were. I do sometimes wish Crank Bros weren't quite so purist and put some flats on the pedal axles like any other company
