[kuh n-dish-uh n]

  • a particular mode of being of a person or thing; existing state; situation with respect to circumstances
  • a circumstance indispensable to some result; prerequisite; that on which something else is contingent

verb (used with object)

  • to accustom or inure
  • to subject to particular conditions or circumstances

The primary point is preparing for and becoming accustomed to particular conditions or circumstances. That requires defining what your particular conditions or circumstances and realizing that one can’t realistically claim to condition for “everything.”

Note, the definition of conditioning does not include “flail spastically”, “getting smoked”, “thrashing about for as many reps as possible”, “pushing until you puke”, nor any idiot catchphrases from nitwits in campaign hats.
