The least-resistance philosophy dictates that you should mold your environment so that the path of least resistance is the path of maximum productivity.
The core principles are eliminating barriers to engaging in productive behavior and erecting barriers to engaging in counter-productive behavior.
Admittedly, this philosophy is tricky to apply to an activity that stresses reaching "maximum resistance."
But, the principles still work.
