Description

This exercise is a core exercise that focuses on the external oblique muscles. It involves rolling a ball from side to side while maintaining a plank position.

How to Do Roll Ball External Oblique

1
Setup
Begin in a forearm plank position with a stability ball placed directly under your forearms. Your body should form a straight line from your head to your heels.
2
Setup
Engage your core muscles, ensuring your hips are level and not sagging or lifting too high. Your feet should be hip-width apart for a stable base.
3
Slowly roll the stability ball to one side, allowing your torso to slightly rotate while keeping your core tight and your hips as stable as possible.
4
Control the movement as you bring the ball back to the center, actively resisting any unwanted rotation or dropping of the hips.
5
Continue the movement by rolling the ball to the opposite side, maintaining the same controlled pace and strong core engagement.
6
Alternate rolling the ball from side to side for the duration of your set, breathing steadily throughout the exercise.

Tips

Control the range of motion by only rolling the ball as far as you can maintain a stable plank without letting your hips drop or excessively rotate.
Actively squeeze your glutes throughout the exercise to help stabilize your pelvis and prevent your hips from swaying, which improves oblique activation.
Maintain a neutral neck position by gazing at the floor between your forearms, avoiding any strain on your cervical spine.
Coordinate your breathing by exhaling as you roll the ball to the side and inhaling as you return to the center, maintaining constant core tension.

Common Mistakes

×Allowing your hips to sag towards the floor reduces core engagement; keep your glutes and abs tight to maintain a straight line from head to heels.
×Over-rotating your torso or rolling the ball too far compromises stability; focus on controlled, smaller movements where your core actively stabilizes the rotation.
×Holding your breath can increase intra-abdominal pressure unsafely; remember to breathe steadily and deeply throughout the exercise to support core function.
