ABS
Balance Trainer Side Star Plank
AdvancedStability ball
A rotating side plank built around a BOSU dome for extra instability. Turning from a plank into a side plank and back challenges the obliques, shoulders, and hips while your body constantly corrects for the wobble. A tougher take on the standard side plank.
How to do it
- 1
Stand behind the trainer and place both hands on the dome.
- 2
Walk your feet back into a plank, feet hip width or a touch wider.
- 3
Lift one arm and rotate into a side plank, reaching that hand to the ceiling.
- 4
Rotate back down into the plank position.
- 5
Do your reps on one side, then repeat rotating the other way.
- 6
Keep the core braced and avoid letting the lower back sag.
