If you haven't tried this advanced core exercise before make sure you have a go at it.

 

It is a great exercise for not only your core stability, but also for building your rotational strength through your hips.

 

When you do the exercise make sure you keep your core braced and focus on hip movement (not your lower back).

 

 

 

Start slow and as you get comfortable with the movement you can increase the speed of the rotation so it becomes a faster more powerful movement.
