Now I'm going to demonstrate Lying Twist on an exercise ball. Okay. So you're going to lie down on the ball. Make sure those hips are down on top. So, what you really need to focus on here, you're going to interlace your fingers, like so. Arms straight. And if you notice, I'm going to roll the ball with me as I twist, so you really feel that pinch in the oblique area, which is your side abdominals.
Okay. So, the ball has to roll with you in order to really get that oblique area. If you want to make it a little more advanced, we're going to use a dumbbell. So, an eight pound dumbbell for weighted resistance. Same exact form. Arms straight. So, now you're just going to feel it a little bit more. Okay. And those are two really good exercises for the obliques. And that's how you perform Lying Twist on an exercise ball.
