Exercising to build strong core muscles can significantly improve your quality of life by lessening your back pain and giving you a straight, confident posture. It's possible to strengthen your core through a number of exercises, but using an ab roller provides an alternative to crunches that can challenge your body in new ways.

Beneficial, But Not the Best
Performing rollouts with an ab roller is beneficial because it strengthens nearly 20 muscles with each repetition. Despite the exercise's association with your abs, it actually targets your hip flexors but also strengthens your abs and obliques. Although repeated repetition of this exercise can lead to strong abs, using an ab roller isn't the fastest way to strengthen this region. The American Council on Exercise ranks the exercise ninth on its list of abdominal workouts as measured by muscle activity. The bicycle maneuver generates the most activity in your rectus abdominis muscles. (See References 2, 3, 4 and 5)
