The secret is the Ab Rocket Twister's exercise efficiency technology.

It starts by offering resistance on the way down and on the way back up for double the impact. Get ripped, washboard abs in half the time! It not only works as a great abdominal machine, but also as a pilates assister. It focuses truly on the muscles you want to tone, the abdominals. And it's great for people at home because it puts you in the perfect form.
