Stability ball arm circle plank exercise demonstration.
A great core exercise that targets abs, lower back, arms and your glutes.
How to do it:
1. Place your forearms on a stability ball and extend your legs behind you, hip-width apart.
2. Brace your abs and raise yourself into a plank position.
3. Using your forearms, roll the ball out to the left, in front of you, and back to the right (like a stirring motion) and then pull it back into the starting position (B). That’s one rep.
4. Do 8 to 12, then switch directions and repeat.
