Mistakes in exercise muscles worked? (Ab Wheel)

[AnonJohn]

Looks to me like there is a mistake in the Ab wheel exercise.

Abs (rectus abdominis) are not listed as a muscle worked. Illiopoas are the main target (I think that is incorrect). I would also say that the tricep and quad synergists are missing.

Not sure if this is the right place for such things. Let me know if there is a better one.
