A Shared Language For Training
Terms are tools; clear definitions make better questions possible.
Why A Glossary Matters
Training language borrows heavily from research, coaching culture, and casual internet shorthand, often without a consistent definition across sources. A reader who hears "progressive overload" described three different ways in three different articles has every reason to be confused. This glossary exists so that when Xyjecta uses a term, it means the same thing every time, and so that readers have a quick reference before an appointment with a coach or clinician.
We add new terms gradually as they come up in articles, and we revise definitions when reader questions reveal that our original wording was unclear. The current version reflects updates made throughout 2026.
Intensity
How demanding an effort is relative to a person's current ability or a chosen scale, such as rate of perceived exertion.
Tempo
The timing of a movement, including lowering, pauses, and lifting phases, which can change how an exercise feels even at the same weight.
Adaptation
A change that develops over time in response to repeated stress and sufficient recovery, rather than from any single session.
More Terms Readers Ask About
Beyond the basics above, several terms appear often in reader questions without a clear shared definition. The list below addresses the ones we are asked about most frequently through the contact page.
- RPE (Rate of Perceived Exertion): a personal description, usually on a scale of one to ten, of how demanding a set or session feels.
- Deload: a planned week of reduced training volume or intensity, used to allow recovery without stopping activity entirely.
- Base Work: steady, moderate-effort aerobic activity that builds a foundation for harder sessions later.
- Movement Vocabulary: the basic positions and patterns—squat, hinge, push, pull, carry, rotate—that help people describe what they are practicing.

Using These Terms In Conversation
Start With The Concept
Describe the practical goal before reaching for a specific term, so a coach or clinician understands the intent behind the word.
Ask For A Definition
If a coach uses an unfamiliar term, ask them to define it in plain language rather than guessing from context.
Compare Notes
Cross-check a new term against this glossary or another reputable reference before adopting it into your own vocabulary.
A Word On Precision
"Precise language will not make a session easier, but it will make the conversation about that session considerably more useful."
