When talking about “ten pack abs”, what most people are actually referring to is the visibility and definition of the rectus abdominis muscle. This muscle, located on the front of the abdomen, is responsible for the appearance of the “six-pack” when sufficiently defined and visible. The number of “packs” or sections you see is determined by the tendinous inscriptions that horizontally cross the muscle.
Most commonly, people have three inscriptions, which divide the muscle into six sections, leading to the famous “six-pack.” Some people might have four inscriptions, dividing the muscle into eight visible sections, and an even smaller percentage might have five inscriptions, resulting in a “ten pack.”
Now, to your question about genetics: Yes, the number of these tendinous inscriptions, and thus the potential for a “six-pack,” “eight-pack,” or “ten-pack,” is largely determined by genetics. In other words, the genetic code you inherited from your parents plays a significant role in determining how many sections or “packs” you can visibly achieve.
However, it’s essential to remember that merely having the genetic potential for an eight-pack or ten-pack doesn’t mean they will automatically be visible. Body fat percentage, muscle development, and overall fitness play significant roles in the appearance of the abs. You need to have a low enough body fat percentage for the sections to be visible, and the underlying muscles need to be well-developed through exercise.
While the potential to have an eight-pack or ten-pack is influenced by genetics, achieving the desired visibility and definition requires dedication to a proper diet and exercise routine. Many individuals can work towards and achieve a chiseled six-pack with commitment, but the exact number of visible sections will be a blend of genetics and effort.
