Workout Abdominal Exercises- Curl Ups

Many exercises tone the abdominal muscles. The trick is to choose those workout abdominal exercises that target the ab core muscles, while minimizing the activation of the hip flexors and stress on the spine.

Bent-knee sit-ups for workout abdominal exercise, without foot support and hands at the sides moving 4 inches during the curl-up, produces the greatest abdominal muscle activation, while minimizing the activity of the hip flexors. When doing curl-ups, try to isolate the rectus abdominis (large six-pack muscle) and minimize the movement of the shoulders, head, and neck.

This ab workout lower exercise isolates and overloads the ab core muscles, without overloading the spine and vulnerable neck muscles.
