The Incomplete Rest Method (IRM) is used to create a metabolic stimulus. It’s simple and effective, which is why we use variations of this method regularly when writing certain types of programs for specific stimuli.
The characteristics of an IRM include:
- Can be performed at any training experience level (easy to individualize)
- Increases nutrient partitioning (shuttling nutrients preferentially to muscle instead of fat)
- Minimal mechanical damage
- Minimal oxidative stress
- Minimal neurological stress
- Activates AMPK (signals muscles to store glucose and burn fat simultaneously)
If you’re not familiar with some of the terms in the last 4 points, that is ok. Those are topics we cover in detail in the Nutrition & Program Design course.
What you need to know is that you should usually not do it in a completely glycogen depleted state and that it can be beneficial for fat loss programs because, when done correctly, you will recover quickly meaning you can train at a higher frequency.
