Select and participate in appropriate exercise strategies to enhance flexibility and muscular endurance for teacher-specified muscles through a variety of activities (e.g., design a fitness circuit, lead a class warm-up).

Use the proper names (e.g., bicep, tricep, hamstring) of the muscles when doing flexibility and muscular endurance exercises that benefit those muscles.

Use own body weight to challenge and improve personal muscular strength (e.g., various versions of push-ups, curl-downs, pilates, core strength training) of both the joint muscles and the core muscles.

Willingly engage in a variety of movement activities that promote muscular endurance and flexibility.

Incorporate the use of a variety of objects and equipment (e.g., dynaband, resistance bands, surgical tubing, exercise ball, skipping rope, towel) into muscular endurance, muscular strength, and flexibility challenging activities.

Research and highlight safety guidelines for safe and effective muscular strength development during adolescence.

Discuss and implement resistance training exercises as a means to develop muscular strength.

Express an understanding of the inappropriateness of power lifting and single-joint focused weight lifting as a strategy to improve muscular strength when the body is not fully developed.
