Ter info:

Usually, when one is trying to target the “lower abs”, they do various types of Leg Raises. Sometimes people do them while hanging from a chinning bar. Other times they are performed while one is suspended by the elbows in a type of abdominal chair. Still another version is where one lies on the floor, and performs Leg Raises in the horizontal position. We’ve been told for years, by misguided coaches and trainers who have been taught this theory by other misguided trainers (i.e., the blind leading the blind). “Leg raises are good for lower ab development”, they’ve told us. But – as you can see from the illustration above – the abdominal muscles are NOT connected to the legs at all, so why would raising the legs work the abs?

There is a secondary participation of the Rectus Abdominus when we perform Leg Raises. In other words, while the “hip flexor” muscles (the ones that attach to the legs, but are NOT abdominal muscles) pull the legs up, the abdominal muscle typically acts as a torso stabilizer during that movement (…otherwise, the spine would buckle). The ab muscle is not the primary muscle working during a Leg Raise, even though it may be your primary target. It makes no sense to do an exercise that is 80% legs (hip flexors), and 20% abs, instead of doing an exercise that is 100% abs, if your primary objective is abdominal development.

But more to the point, the 20% (approximately) of ab muscle stimulation that results from Leg Raises will NOT be working the lower portion of the abs any more than regular ab crunches will. To the degree that your Rectus Abdominus is working during leg raises, the entire muscle works – from top to bottom.
