A warm-up is preparatory activity intended to improve readiness for the session that follows.
Why it matters
Warm-Up affects how a program feels, how it is scheduled and how progress is interpreted. Understanding the term helps readers compare programs more accurately instead of relying on labels alone.
Example
Two programs may use the same exercises but apply different warm-up choices. That difference can change session length, fatigue, technique demands and the amount of recovery required.
How it is used in programs
Program designers use warm-up to organize training and control difficulty. It should be adjusted in relation to the person’s goal, experience and ability to recover.
Common misunderstanding
A common mistake is treating warm-up as a quality score. More, faster or harder is not automatically better; the useful amount is the amount that supports the intended adaptation while preserving repeatability.
