Relevancy

Fitness

Excellent exercise for intermediate and advanced fitness enthusiasts who want to test the functionality of their bodies.. The exercise is fantastic for many people, however it is too advanced for another.


  • If you're an advanced athlete you can implement the ab wheel rollout as a first / second main exercise in a workout for abs.

Power and strength-conditioning workouts 

The Ab Wheel Rollout offers many benefits of including it into a workout program. In addition to test the stability of the joints, maintain and power scaling of the abdomen, hips constrictor, dorsal muscles. Improves control of pressure in the abdominal belt which is so needed in one-rep maxes.

Fitness 

Classic bodybuilding programs may not benefit from this exercise - the movement does not affect visual improvements and carries a risk because of its complicated technique. It does not combine too well with pre-exhaust exercises in ab workouts which are in most workout programs.

Ghetto-workouts

This exercise is perfect for training at home/outside.The roller is small and you can carry it easy within your backpack.

Crossfit

It is usually implemented as a final exercise in crossfit circuits.However beware of over-exhausted stabilisers and sygergists while performing this exercise in a crossfit circuit.
