Karate Chop

Start standing with your left hand on a sloping rail and your right on a low sidepull/undercling. Pick some feet, pull on and throw for the lip. Repeat as necessary. (Hint: Many people prefer using the good, low foothold out right. Though I've seen people do it with a higher foot as well.)

Top out a bit to the left as per 'Global Chop Suey'.

Much easier for those taller in stature.
