What is the command for changing positions in the Side Bridge exercise?

In the context of the Side Bridge exercise within the Army Physical Readiness Training (PRT) framework, the proper command to change positions is indeed "Change Position, Ready, EXERCISE." This command is specifically designed to instruct individuals to transition into the exercise properly and ensures that they are prepared for action while maintaining the safety and structure required during physical training.

This command sequence is crucial because it provides clear, actionable directions that facilitate a smooth transition into the exercise posture. By using "Change Position," it clearly indicates that the trainees should move into a specific formation or exercise position. Following this with "Ready" establishes that the participants should be prepared and focused on executing the exercise safely and effectively. The final part, "EXERCISE," signals the start of the actual movement.

The other options do not correctly capture the established commands for the Side Bridge exercise, which could result in confusion or ineffective execution of the exercise. The commands provided are standardized as part of PRT to maintain consistency and effectiveness across all training sessions.
