This post was mark “unapproved” on the moderated training forum, so I’m posting it here to be sure it’s seen.
Defining “training stimulus” as the nuts & bolts of a program (sets, reps, load) and “training stress” as the resultant load placed on the individual based on fitness level, performance potential, etc., does training stress ever truly need to increase to continue to drive further fitness adaptations, or is the stimulus simply being modified to apply the necessary stress?
