Question 3

How many total phases are in the OPT Model?

Accepted 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?

Accepted 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?
