Power Series Abdominal Crunch & Back Extension Pin Load

The Power Series Abdominal Crunch & Back Extension Pin Load pairs two complementary trunk movements in one commercial station. Members work the abdominals through a guided crunch, then train the spinal erectors with a supported extension — all from the same selectorized pin-loaded weight stack. Multiple adjustment points and a body-contouring seat set up each movement correctly, making it an efficient core station for space-conscious, high-traffic facilities.
