Description
The Full Sit Up is a classic abdominal exercise performed by lying on the back and fully raising the torso, working both the upper and lower abdominal muscles. Unlike the crunch, the range of motion is full (from lying flat to a seated position). It activates all fibers of the rectus abdominis, hip flexors, and core muscles. It is one of the foundational movements of military training and functional workouts. The full range of motion heavily engages the hip flexor muscles, making it a compound movement. It also improves hip mobility and torso flexion strength. Being more challenging than the crunch, it is suitable for intermediate athletes. When performed regularly, it provides significant improvements in abdominal development, hip flexor strength, and overall core endurance.
