At the University of Houston's Department of Human Performance, extensive Electromyographical (EMG) tests were performed on a wide range of subjects, young and old, male and female. The Quantum® PowerCrunch 1200 (QWT-145) out-performed all major abdominal floor exercises (up to 51% greater involvement in the upper region of the rectus abdominis and 44% greater in the lower region).

Resistance can be increased on the Quantum® PowerCrunch 1200 (QWT-145) to keep pace with progression in developing the six pack by simply adding weight to the built in weight peg.
