Montaque, I share your laughter. And if it looks hard, all the more reason to try one out. Your working the full range of the ab wall, plus the obliques, with one exercise.. The lat's and upper back are also recruited, but try keeping the focus on the function of the abs themselves. If having lower back problems (herniated disc, etc...or even a potential ab hernia) this movement may not be for you until the problem is corrected. The closest thing to this exercise, with weights, would the the straight arm pullover, with the bent arm pullove following.
For folks who never used one before, best to start with the knees on the floor. Some try for a full extension the first time they use a Ab Wheel and find they can't get back up, so maybe a few dozen half reps to start out, for a few workouts. The body will adapt quickly, so starting with the toes on the floor shouldn't take long. As advancing, put the feet on a box, chair or even table. That girl (I think) gives an excellent example of the standing roller movement. That is a good goal to shoot for, if getting serious about this exercise.
Usually done on a smooth surface (gym , hardwood, cement floor, etc), trying it on a light rug will offer more resistance. On a heavy ply rug, not so much success for most people. Some will have a BB plate placed on their backs, though extreme for most folks.
There are single and double wheel rollers, and though they may look not that solid, they tend to be. For a $5 investment, can't go wrong. Good Luck.
