Hello, I started working out consistantly since November 2019 and i have developed some decent abs. I put on around 20 lbs since then, but recently i noticed my upper left abdominal muscle is missing and when i work abs I dont feel any fatigue in that area but i feel fatigue in my other ab muscles. I had surgery as a new born on my liver so im wondering if that maybe caused some disruption in the growth of that muscle, but i wouldnt think it would completely stop growing especially being 20 years later. If you could maybe help me and try to figure this out that would be great!
Looks all good to me, i see no issues from the pictures. Its possible one side has more pain tolerance than the other side.
