Meet Your Team of Olympic Weightlifters
Imagine that inside each of your muscles lives an entire team of Olympic weightlifters.
Some are lightweights.
Some are middleweights.
And some are massive heavyweights capable of producing tremendous amounts of force.
Those “lifters” are a simple way of thinking about something called motor units.
When your brain asks a muscle to produce force, it doesn’t necessarily use everything it has.
Instead, your nervous system recruits motor units in an orderly fashion, from lower-threshold units toward higher-threshold units, as the force requirement increases.
This is called the size principle of motor unit recruitment.
Think about picking up a coffee cup.
Your body doesn’t need its heavyweight Olympic lifters for that.
So it doesn’t call them.
But now imagine trying to pick up something substantially heavier. Maybe a bag of dog food or mulch.
The smaller lifters aren’t enough anymore.
Your nervous system must start calling in reinforcements.
Eventually, if the demand becomes high enough, you’re asking those larger, higher-threshold motor units to contribute.
And that’s incredibly important if your goal is strength.
Because if you’re training never creates enough demand to challenge your higher-force capabilities, you’re leaving a significant part of your strength potential untrained.
This is one reason why simply doing more and more repetitions isn’t the same thing as training specifically for strength.
You’re asking your body to solve a different problem.
And the body becomes remarkably good at solving whatever problem you repeatedly give it.
Want to improve endurance?
Train endurance.
Want to become stronger?
At some point, you must give your body a reason to produce greater force.
You have to call in the heavyweights.
But there’s an important catch.
You shouldn’t just walk into the gym tomorrow, throw twice as much weight on the machine, and hope everything works out.
There’s a process.
And skipping that process is exactly where many people get into trouble. It’s the thing we all fear; getting hurt!
We’ll talk about that next.
