Which of the following is NOT one of the prep drill exercises?

The prep drill exercises serve as a foundational component in many physical training regimens, particularly in military or tactical settings. They are designed to warm up the body, increase flexibility, and prepare muscles for more intense physical activity.

Among the listed options, the 'Roadrunner' is not recognized as one of the standard prep drill exercises. The other three exercises—Windmill, Squat bender, and The rower—are established components of prep drills.

The Windmill helps improve flexibility and coordination while stretching the muscles in the upper body and core. The Squat bender is focused on developing lower body strength and flexibility, specifically targeting the legs and hips. The Rower mimics the motion of rowing, promoting overall body coordination and endurance. These exercises collectively aim to prepare individuals for more demanding physical tasks. By understanding the specific nature of these drills, it becomes clear why 'Roadrunner' does not fit within this structured set of activities.
