Use a combination of vinegar, honey, whiskey and olive oil. Makes it slip like crazy. Although honey may sound counter-productive, it functions as a stabilizer, which makes the remaining ingredients 'stick' (in a molecular sense) together to produce a more slippery product. Trust me, it's my private recipe.

As for the techniques, you should prioritize on mental preparation above physical stimulation. The mind controls the body, so imagine yourself doing who you please and you'll arrive at your destination.
