Based on the available information, it can be stated that Lipitor, a medication used to treat high cholesterol, does not have a direct impact on flexibility. Lipitor, also known as Atorvastatin, is a type of drug called a statin, which reduces the levels of low-density lipoprotein (LDL) or "bad" cholesterol in the blood [2].

Although Lipitor is not known to improve flexibility, it can help prevent cardiovascular diseases by lowering cholesterol levels [1][2]. High cholesterol can lead to atherosclerosis, the hardening and narrowing of the arteries, which can reduce blood flow to the limbs and potentially cause pain and decreased flexibility [3]. Therefore, by controlling cholesterol levels, Lipitor may indirectly help maintain flexibility and mobility in individuals with high cholesterol.

However, it is important to note that Lipitor's primary purpose is to manage cholesterol levels and reduce the risk of cardiovascular events, and it should not be used solely to improve flexibility [2][3].
