The OPT Model

The OPT Model, or Optimum Performance Training Model®, is a fitness training system developed by NASM. The OPT Model is based on scientific evidence and principles that progresses an individual through five training phases: stabilization endurance, strength endurance, hypertrophy, maximal strength and power.


NASM Optimum Performance Training (OPTTM) Model®

With the power of OPT, you can take what you learned in NASM's Certified Personal Trainer (NASM-CPT) program, and apply it quickly and confidently from the moment you start working with your first client.

With this easy-to-use model, you'll be able to help clients achieve their fitness goals, no matter their age or athletic ability - from beginners, to pros.

The OPT model - and NASM as a whole - is simply powerful.

OPT has been extremely successful in helping clients from diverse populations reduce body fat, increase lean muscle mass and strength, and improve overall health and performance.
