I tasted a little more success with the 'rocking' technique this week. [I've learned from @ryankleech that 'rocking' allows you to pause and reposition each of your tires for a more optimal line — typically for a technical obstacle — by using body movement against locked brakes.] Rather than trying to rock in place (see my video from 3 weeks ago), I decided to try adding rotations to the rhythmic rocking. I was trying to rock & rotate to the right with my left foot forward, and then rock and rotate to the left with my right foot forward. I'm a long way from getting to where I'll be able to use it on the trail but having really 'felt' it for the first time, I'm pretty confident I'll get there.
