After reviewing the provided sources, there is no direct evidence that suggests that Lipitor affects exercise frequency. Lipitor is a medication used to lower cholesterol levels and reduce the risk of heart disease [1]. According to a study published in the Journal of Clinical Lipidology, Lipitor did not have a significant effect on exercise capacity or frequency in patients with high cholesterol levels [2].

However, it is important to note that some individuals may experience muscle pain or weakness as a side effect of taking Lipitor [3]. This could potentially affect their ability to exercise, but it is not a common side effect and would likely vary from person to person.

Overall, Lipitor is not known to directly affect exercise frequency. It is always recommended to consult with a healthcare provider before starting any new medication or exercise regimen.
