I understand you're frustrated, my point is maybe you are just going about training them wrong. Sometimes keeping it simple and not over-complicating things is best. Practice doing situps everyday, don't fatigue your abs on other ab movements. You have a specific goal and that is to do more situps, so that's what you need to do, more situps.
