Question 1
What does OPT stand for in the NASM OPT Model?
Answer: OPT stands for Optimum Performance Training. It is NASM's systematic, periodized training approach designed to achieve optimal levels of physiological, physical, and performance adaptations.
Question 2
What are the three building blocks (levels) of the OPT Model?
Answer: The three levels are Stabilization, Strength, and Power. Each level contains specific phases that progress in complexity and demand.
Question 3
How many total phases are in the OPT Model?
Answer: There are 5 total phases in the OPT Model. Phase 1 is Stabilization Endurance, Phases 2–4 are Strength phases, and Phase 5 is Power.
Question 4
What principle is the OPT Model based on that involves systematically progressing exercise variables over time?
Answer: The OPT Model is based on the principle of periodization — the systematic manipulation of training variables (sets, reps, intensity, rest) to avoid plateaus and optimize performance.
Question 5
Which population is Phase 1 of the OPT Model most appropriate for when starting a training program?
Answer: Phase 1 is most appropriate for deconditioned beginners, those returning from injury, or anyone who needs to establish a base level of neuromuscular efficiency and stabilization before progressing.
