Lipitor is a brand name for the drug atorvastatin, which is a statin used to lower cholesterol levels in the blood [1]. According to the Mayo Clinic, some of the side effects of statins include muscle pain and damage, liver damage, and an increased risk of developing type 2 diabetes [2]. However, the article also states that exercise can be beneficial for people taking statins, as it can help improve cholesterol levels and reduce the risk of heart disease.

A study published in the Journal of Clinical Lipidology found that moderate exercise did not increase the risk of muscle damage in people taking statins [3]. The study also found that exercise can help improve muscle function and reduce muscle pain in people taking statins. However, the article notes that people taking statins should still be cautious when exercising and should speak with their doctor before starting a new exercise program.

In summary, exercise can be beneficial for people taking Lipitor, as it can help improve cholesterol levels and reduce the risk of heart disease. Moderate exercise is generally safe and does not increase the risk of muscle damage in people taking statins, but it is important to speak with a doctor before starting a new exercise program [2][3].
