Because it's like those balance balls that people use at the gym. Basically your body is constantantly working to balance so it's making your core work to balance itself out. It also improves your posture because you are forced to stand straight to balance out. They work you out when you don't even realize. I read on Twitter that this guy Scout (he is friends with Tori Spelling and on her show) bought a pair and wore them for a few days walking in New York. He said he wasn't sore from walking all day and that after wearing them for a few days he had to get a size smaller pair of pants from losing weight. He was singing the praises of the Shape Ups!
