Acute variables are the most fundamental component of program design. Regardless of the OPT level, correct manipulation of the acute variables ensures the most effective programming possible.

Respond to the following:

What are three (3) specific examples of how acute variables differ across the five phases of the OPT model?
When is it most appropriate to progress a client to a higher level of the OPT model? What methods of progression should be used for each level?
What are some indications that your client requires you to progress or regress an exercise? Additionally, choose three (3) exercises and provide a regression and progression for each.
Choose three (3) modalities commonly used in the gym, and explain how you could use each to progress and/or regress an exercise.
