Nemeo’s take

The Janda Sit-up is an elite ab variation designed to isolate the rectus abdominis by eliminating the involvement of the hip flexors. Its name comes from Dr. Vladimir Janda, who used the principle of reciprocal inhibition: by actively contracting the hamstrings and glutes, the body nervously “deactivates” the iliopsoas. It's the "big brother" of precision: unlike the classic sit-up where you pull with the hips, here, each centimeter of the rise is generated solely by the abdominal strap.
