Spring Wall Hundreds

This is the Hundreds for the oblique abdominals. You stand perpendicular to the spring and put a baseline of tension into the spring. Then you pulse the ring with your shoulders, like a heartbeat. Your abdominal wall, especially the oblique abdominals, must stiffen in order to create a solid base of support for your arms to work against. You will really feel your abdominal wall tighten around the circumference of your trunk.
