Scaling means adjusting a workout's weight, reps, range of motion, or movement to match your current ability while keeping the intended stimulus. It is how a true beginner and an experienced athlete can train the same session safely and both get the right challenge.
A plain-language definition from the CrossFit BC glossary. We explain the term the way a coach would explain it mid-class, then show where it fits in an actual training week.
No. Scaling keeps the intended stimulus while matching the work to your ability. A scaled workout is the right workout for you, and most members scale something on most days.
Your coach guides it, especially when you are new. As you gain experience you learn to self-scale based on how a workout is meant to feel.
