Who invented sit ups

The Janda sit-up ingeniously inactivates the hip flexors by contracting the hamstrings and glutes. He then asked the patient to pull against his hands as they attempted to sit-up. Presto, the hip flexors are inhibited by the contraction of the opposing knee-flexor hamstrings and the hip-extensor glutes. The result, according to Dr. Janda, is true isolation of the abdominal muscles. It sounds good, but as I discovered the execution is tricky. Pressing against the wall engages the hip flexors and pushing down on the floor only provides enough leverage to do a crunch.
