Based on the information provided, it is not explicitly stated whether regular exercise alleviates Lipitor's effects on flexibility. However, it is well-known that regular exercise can help manage cholesterol levels, which is the primary purpose of Lipitor (atorvastatin) [1]. Lipitor is a statin medication that lowers cholesterol levels in the blood by reducing the production of cholesterol in the body and increasing the removal of low-density lipoprotein (LDL) or "bad" cholesterol from the bloodstream [2].

Exercise can contribute to maintaining healthy cholesterol levels and overall cardiovascular health. Regular physical activity can raise high-density lipoprotein (HDL) or "good" cholesterol levels and lower triglycerides, which are another type of fat in the blood [3].

In summary, while there is no direct evidence suggesting that regular exercise alleviates Lipitor's effects on flexibility, engaging in regular physical activity is beneficial for maintaining healthy cholesterol levels and overall cardiovascular health, which is the primary goal of Lipitor.
