Last thing, your abdominal muscles will still be YOUR abdominal muscles.
We are all born with a unique genetic structure. Your bone structure is uniquely yours. Your musculature is uniquely yours, etc.
Some people naturally have a big chest based on their genetic structure. Some people naturally have tiny calves based on their genetic structure (aka me).
Some people naturally have thick abdominals and some do not. While this can be influenced to our favor, we must first accept that we will not be able to work our way towards somebody else's abdominals.
I see many beginners buying into the false belief that we can eventually have abdominal muscles that look EXACTLY like a person's abdominals whom we admire. I bought into this false belief myself...
