Difficulty Rating:
One Handed Rock Pivot = find a large rock with a plateaud surface (preferably the one at Carsington Reservoir, Derbyshire). Climb on top of the rock and locate yourself as centrally as possible. Crouch down, place one hand on the surface and lock your elbow under your stomach/groin. Slowly transfer your weight so that your whole body is balanced on that arm. Finally, straighten your legs and extend your other arm so that you are parallel to the rock surface.
