What does the term "bump-up" mean in high school wrestling?

The term "bump-up" in high school wrestling refers to the action of competing at a higher weight class than the wrestler's designated or typical class. This may occur for various reasons, such as attempting to face tougher competition, helping the team by filling a weight class that might otherwise be vacant, or adjusting to the wrestler's physical growth.

Wrestlers might "bump up" to test their skills against stronger opponents or to challenge themselves in a different weight category. This strategy can often enhance the wrestler's experience, as it may build resilience and adaptability, important qualities in their overall development in the sport.

The other options refer to different actions in the sport, such as staying in the same weight class or wrestling at a lower weight class, neither of which align with the "bump-up" concept, nor do they address the situation where a wrestler changes teams mid-season, which is a separate issue entirely.
