Specificity, Individuality, Overload and Variation in Program Design

Karen Litzy talks with Nick, a trainer of more than 20 years and the 2016 NSCA Personal Trainer of the Year, about his principle-based approach to program design. His argument is that the four principles stack: each one informs the next rather than standing alone. Specificity comes first, because the goal determines the method. For strength he uses longer rests and about four to six sets of four to six reps; for hypertrophy an undulating mix of rep ranges across the week; for metabolic cost a tri-set of dumbbell press, hip thrust and row kept around one bench. Choosing methods by personal preference, such as powerlifting or Pilates, puts methods above principles. Individuality then filters the options by the person's medical history and limitations and by their training environment, such as a crowded gym or a home setup with light dumbbells. Overload keeps progress going within those limits, and variation takes over when adding weight or reps stalls, before the cycle repeats.
