阅读理解。 We've all en them: perfectly toned famous people on late-night television telling us that we too can develop rock-hard abdominal muscles(腹肌). It's easy! Just pay $149.99 for the Torso Track or $149.75 for the Ad-Doer and watch tho unwanted inches leave your waist. Americans spend tens of millions of dollars on various products to firm up their fat around the waist. And did they work? Not necessarily. Independent studies have concluded that most of the products ---- no matter who approved them orhow expensive they are ---- shape your midction no better than old-fashioned stomach crunches(仰卧起坐). Some can even cau injury ---- like the $518.99 Body Shaper-Q8SP, which left electrical burns on some rearchers at the University of Wisconsin, La Cros. Others, like the popular Ab-Doer, typically burn less energy than a gentle walk, according to a study to be published in September by theAmerican Council on Exerci. The fact is that many Americans don't have the biological makeup to develop an obvious abdominalmuscles. They are either unable to get the necessary muscle mass or they can't lo enough fat to make a difference. Even if the underlying muscles are well developed, all it takes to hide it is one-sixteenth of aninch of fat. That's enough to exclude most healthy women as well as plenty of guys who do crunches every day.   So what works best? In its new study, the exerci experts rearched on the results of the popular Ab-Doer. A lengthy TV advertiment promis that just 10 minutes a day performing such movements as "Body Boogies" and "Good Mornings" will "help form tho muscles the fun and easy way without diets." Steven Loy, professor at California State University, Northridge, tested the promi by measuringthe electrical activity produced by the abdominal muscles during three Ab-Doer movements. He and his colleagues then compared the results with tho produced during traditional exercis. They determined that the muscles were no more active, and in some cas less so, when exercirs were using the Ab-Doer. Taking a broader approach, rearchers at San Diego State University compared 13 abdominal exercis for their ability to develop the central abdominal muscles. They concluded, in a report publishedin May, that the most effective exercis kept turning the body and worked the muscles the entire time. Among the winners: the bicycle movements ---- so called becau it looks as if you are riding a bike while lying flat on the floor ---- and exercis performed on the "Captain's Chair", a product typically found in gyms that helps hold the body in the air while you rai your legs up toward your chest. Rearchers suggested that a varied routine of the different exercis could deliver the best results.1．Which of the following is the most effective in building abdominal muscles?A．Torso Track.B．Ab-Doer.C．Captain's Chair.
