Six packs challenge: Day 24 - My workout seems din't workout

It seems no improvement at all since Day 15 until today. I started to question is my workout din't workout? Or I should change my meal plan? Or I should work out more on each part of muscle? Am I on the right track but need more time? Or the improvement is too little to be seen with eye?

Thought of the day

When I Google for six pack exercise, six packs meals, six packs training, incredible abs, abs workout... There are many things come out. I believe all kind of knowledge lead to self-knowledge. Let's say one article wrote "To have six packs, you must sit-up 100 times a day for 100 days". They may not wrong, but there are many factors. Body fat, what kind of food to eat, this and that. I believe should everyone should have an own workout and food schedule based on body fat. A person with 30+% sit-up 100 times a day may just waste his or her time. For example.

16% Body fat - what to do? More on cardio, eat food with low fat or without fat.

13% Body fat - what to do? More on cardio, start a little workout, eat only food that benefits your body.

11% body fat - what to do? what should do?

8% body fat - what is the best to do?
