Summary: Without the proper technique, extensions can make you sick. Learn how to do extensions with stability balls in this free exercise video from a certified Pilates instructor.
"If you don't have a lot of arm strength, we can also do extension with the stability ball underneath the ribcage. So bringing the ball right about here, you want it under the ribcage, not in your stomach, otherwise it can make you feel a little sick. You're going to come down like this. You're going to go ahead and bring the arms up and we can come up and then come over the ball. And exhale up, close that ribcage, inhale, rollover, stretching out the spine. Exhale up. We can do the three arm positions where we inhale over, and exhale up. Legs are long and strong. Glutes are engaged. The other arm position looks like this. Take a nice inhale and come over and exhale up and the ball is nice and supportive. We can also go swimming and do our breast stroke. So we'll start with our arms like this, take a nice inhale and exhale come up, shoot the arms out, inhale around. Shoot the arms out, inhale around. Shoot the arms out, inhale around and inhale around and then the other, the dog paddle."
