About this exercise
Crunches are a bodyweight exercise that primarily targets the rectus abdominis, the muscle group responsible for the "six-pack." This exercise involves flexing the spine, lifting the upper body towards the knees while keeping the lower back stationary on the ground. Crunches help improve core strength and endurance, making them a staple in many abdominal workout routines. By isolating the upper abs, they enhance muscle tone and stability in the abdominal region, contributing to overall core strength development.
