Which is NOT one of the three factors that should be included in a flexibility workout?

In a flexibility workout, the primary focus is on improving the range of motion of the joints and enhancing overall flexibility. This typically involves incorporating various types of stretching. Static stretching refers to holding a stretch at the end range of motion, which helps to lengthen the muscles. Dynamic stretching involves moving parts of the body through a full range of motion, often used as a warm-up to prepare the muscles for activity. Active stretching engages the muscles during the stretch, promoting flexibility and strength.

On the other hand, resistance training is primarily aimed at building muscle strength and endurance rather than specifically enhancing flexibility. While it can indirectly contribute to a greater range of motion when properly performed, it does not fit within the core components specifically designed for a flexibility workout. Consequently, it is the factor that does not belong in a flexibility-focused exercise routine.
