Site Add Ab Doer Twist Please?

I love this app, I'm not entirely loyal to working out as I should be, but I'm trying. But, one of my favourite/main work out methods is the Ab Doer 'Twist'. I want to add it to my Daily Entry, but can't because it doesn't recognize it. And I have no idea how many calories I am burning on it. My Fitness Pal: Please Add it as an exercise in the search
