How is the curl-up exercise performed during the PFA?

The curl-up exercise is performed correctly by lying on the back with the knees bent and curling up to touch the knees. This position is essential as it engages the core muscles effectively while allowing for proper spinal alignment and range of motion. During the exercise, participants focus on contracting their abdominal muscles to raise their upper body towards the knees, which promotes core stability and strength. Additionally, starting from a supine position aids in minimizing strain on the lower back, making it a preferred format for fitness assessments. This method ensures that the exercise is executed safely and efficiently, aligning with the standards expected during the Physical Fitness Assessment (PFA) in the Navy.
