Muscle Prodigy explains that the three variations are considerably different from their conventional counterparts; therefore, each is more effective. For example, the Janda-style sit-up requires the athlete to pull his upper-body downwards on an inclined bench against the resisting force of a companion while the lower legs and glutes remain fixed in place. This keeps the focus on the abdominal muscles and discourages the contraction of the hip-flexors, which assist in conventional sit-up variations.
