Ab Wheel Rollouts Are a Great Way to Build Core Strength, Improve Balance and StabilityAb roller workouts improve core strength because you need to stabilize your spine in order to perform the exercise correctly. It also helps in improving your body's ability to balance which comes in handy when doing sports.
For example, integrating ab wheel rollouts into your workout will make you better at sports such as football because body balance is a key element in that game.2
An Ab Wheel Is More Effective Than Crunches or SitupsAn ab wheel can do what 100 sit-ups cannot because it engages your core muscles from head to toe and helps you build up a nice six-pack quickly.  
An ab wheel exercise produces a significant amount of more muscle activity in your abs and obliques than traditional crunches.
If you compare the work done by abs muscles when doing crunches, you will find that ab wheel rollouts require less effort but more use of your core muscles than sit up and crunch.
Works Out a Large Number of Muscle Groups If you really want to work out all your muscle groups at once, ab wheel rollouts are the best way without a doubt. Ab roller exercises strengthen your abs, shoulders and arms while burning fat from all over your body.
An ab wheel can work up to 20 different muscles at once. In fact, it engages more than just your abs because you will need to tighten all the major muscle groups in your core, back, and arms to perform ab wheel rollouts properly.
It simplifies the process of targeting multiple muscle groups as opposed to using a machine that only works on one part of your body or isolating your abs with traditional crunches.
It's a Full-body Cardio Workout An ab wheel is really good for working out your lower body muscles, plus the integrated movement of rolling the wheels forward and back will get your heart rate up quickly. Performing ab wheel rollouts activate the both upper an lower extremities as you rotate while doing them.
