I saw this video where a guy shows he has a 10 pack. Then in the comments people explain the human body only has 8 ab muscles. Some claim the bottom two muscles are implants.

enter image description here

Can this be real, or does he actually have surgically implanted fake bottom abs? I'm curious to know if its really possible.

    See also 8 abdominal muscles but 10 pack on Biology.SE – ChrisW May 13 '17 at 10:58
  • I've always understood the N-pack to refer to horizontal bands, so that would be a 5-pack. – jamesqf May 13 '17 at 16:29
  • @jamesqf but the bottom 4 each seem to have a vertical crease in the center rather than being a horizontal band. – J.Todd May 13 '17 at 17:25

    Seems plausible that this might be done with synthol. If you search for synthol and bodybuilding, there're tons of pictures of crazy body shapes achieved with it. Dunno about a 10-pack of abs, but seems like a reasonable possibility; two of the abs would just be from the oil. The other 8 might be as well, or they could be real, or partially real. The coloration in that photo looks suspicious, though, so it could also be Photoshop. – Nat May 14 '17 at 1:52
  • @Nat Oh wow yeah it could maybe be that. Not photoshop though because in the video you can see them clearly. – J.Todd May 14 '17 at 5:04

Possibly real, but not "10 (or even 8) 'ab muscles'"

The appearance of compartmentalized 'ab muscles' is due to an anatomical structure called the abdominal linea alba.

It is common for there to be three 'tendinous intersections' (on each side) which create the classic 'six-pack' appearance -- however, studies of cadavers indicate that, due to genetic variations, four or even five are possible; a different study found again that three was most common, but noted that two or even just one was also possible.

Again, these are genetic variations and having a 10-pack is not indicative of superior physical fitness compared to those mere mortals who can only muster an 8-pack.

    "but noted that two or even just one was also possible." I knew it. – fredsbend Nov 26 '18 at 22:49
