Final answer:
Before showing a resistance exercise, an instructor should explain the exercise's purpose, demonstrate proper technique, and review safety guidelines. This ensures participants understand and perform the exercise safely.
Step-by-step explanation:
Before an instructor begins to show an exercise involving resistance, they should explain the purpose of the exercise, demonstrate proper technique, and review any safety guidelines. This preparation helps ensure that participants understand why they are doing the exercise and how to perform it safely, minimizing the risk of injury. It's also essential for instructors to consider the fitness level of their students and to provide modifications for those who may need them.
For example, if the exercise is part of a collaborative exercise where the class collectively discusses the number of sweaters owned, the instructor should provide clear instructions before starting the activity. If part of a peer review exercise it is important to read the peer review exercise, tool, or instrument provided by the instructor, comprehensively understand it and then provide feedback to peers.
In a laboratory setting, safety is paramount. Prior to an antibiotic resistance mini project, instructors are advised to deliver an introductory lecture that combines check-in and safety training. This upfront preparation ensures that students embark on their laboratory work with a clear understanding of the project and the necessary safety precautions.
Moreover, when conducting exercises that involve physical exertion, such as a drill instructor encouraging marine recruits to exert maximum effort, it's important to discuss and enforce safety guidelines to prevent overexertion and muscle damage.
