Klymer Glossary
Clear definitions for readers who want to follow the conversation without unnecessary jargon.
Core Terms
Words used in performance writing often carry more than one meaning. These definitions describe how Klymer uses them in general editorial discussion; they are not personal assessments or clinical conclusions.
Progressive Load
A considered change in challenge over time. The change may involve weight, duration, range, density or complexity, and does not have to occur every session.
Perceived Effort
A person's reported sense of how demanding movement feels in the moment. It is useful context, but it can be influenced by sleep, heat, stress and unfamiliar surroundings.
Recovery
The process by which body and mind return toward readiness after a demand. Klymer treats it as a changing observation rather than a fixed score.
Terms In Context
| Term | Ask this question | Common context |
|---|---|---|
| Capacity | What can be repeated with quality? | Endurance, strength and daily activity |
| Readiness | How prepared does today feel? | Sleep, mood, effort and warm-up |
| Volume | How much work was completed? | Sets, repetitions, distance or time |
| Intensity | How demanding was the work? | Load, speed, resistance or effort |
Reading A Definition
- Identify the term and the sentence around it.
- Notice whether the writer means a measurement, a feeling or a planning idea.
- Check environmental details such as heat, terrain and available equipment.
- Avoid transferring a general definition into a personal conclusion without appropriate guidance.
Precision is not about using more technical words; it is about making the meaning easier to check.
Use Terms Carefully
Definitions are context-dependent. A qualified professional can explain what a term means for a specific person, diagnosis or training goal. Klymer's articles explain general language, while the site's disclaimer sets clear limits around individual interpretation.
- Read the surrounding paragraph.
- Compare the term with the date and source.
- Ask for clarification when a definition affects an important decision.
Quick Reference
What is a trend?
A trend is a pattern across several observations, not a single unusually easy or difficult session.
What is consistency?
Consistency means a manageable pattern that can be revisited; it does not mean every day looks identical.
What is context?
Context includes the circumstances around an observation, including schedule, environment, sleep and competing demands.
Keep A Personal Vocabulary
When reading, note which words describe an experience and which describe a measured quantity. This small habit makes conversations with coaches and professionals more precise.
