When to Use Jargon (And When It Gets in the Way)
I'm not a big fan of jargon.
Most of the time, it's used when simpler words would work just fine. Writers swap "build muscle" for "hypertrophy" or "good form" for "movement mechanics," and then a simple idea sounds far more complicated than it needs to be.
The problem is that jargon often creates distance between you and your reader.
If you're writing for everyday gym-goers, clients, or people trying to improve their health, clarity should always win. Your reader shouldn't need a fitness dictionary to understand what they read. They should be able to read a sentence once and immediately know what you mean.
But jargon isn't always the enemy.
If you're writing for coaches, personal trainers, physical therapists, or experienced lifters, technical terms can actually make your writing more efficient. Sometimes "RPE," "periodization," or "hypertrophy" conveys an idea more quickly because your audience already understands the language. In those situations, jargon becomes a useful shortcut rather than a barrier.
The key is knowing who you're talking to.
Too many fitness writers use jargon to sound smart. The irony is that knowledgeable coaches are often the best at making complicated ideas sound simple.
A good test is this: if you were explaining the concept to a client after a workout, would you use that term? If the answer is no, consider replacing it. If the answer is yes, and your audience would understand it, then it probably belongs.
The goal isn't to impress people with vocabulary.
The goal is to communicate clearly enough that people understand, trust you, and take action.
What's one fitness term you use regularly that most clients don't understand? How would you explain it in plain English?
