Grab the handles of the ab wheel, and place your full weight on the device
From this kneeling position, cross your legs behind you, and lift your feet off the mat (this will help stabilize you but make the movement a bit more challenging)
Next, I want you to lock your shoulders into place, and keep your back in neutral alignment
In fact, you could even round your upper back and maintain a semi-rounded position throughout the exercise
As with all functional exercises, brace your core tight and squeeze your glutes (this will bring your hips into a neutral position)
Begin the movement by rolling the wheel out in front of you while keeping your core tight
It is CRUCIAL that your torso alignment does not change throughout the movement
If your lower back position changes IN ANY WAY, you are defeating the purpose of this exercise
Roll out only as far as you can keep you low back straight!
Pause for a second at the fully extended position, while keeping your core tight
Reverse the movement by tightening your ab muscles even further and returning to the starting position
Don’t forget to keep your elbows straight the entire time.
