Based on the provided sources, there is no direct information to suggest that Lipitor, a medication used to lower cholesterol levels, has a direct impact on yoga performance.

The first source, Drug Patent Watch, provides information about Lipitor but does not mention anything about its effects on yoga performance [1].

The second source, a study published on PubMed, focuses on the association between statin use (including Lipitor) and physical activity levels. The study found that statin use was not significantly associated with reduced physical activity levels [2]. However, this study does not specifically mention yoga performance.

The third source, a research article published on PMC, discusses the potential side effects of statin medications, including Lipitor. It highlights that while muscle-related side effects are possible, they are relatively rare. The article does not specifically mention yoga performance as a side effect or as being affected by Lipitor [3].

Therefore, based on the provided sources, there is no direct evidence to suggest that Lipitor affects yoga performance. However, it is important to consult with a healthcare professional or pharmacist regarding any potential concerns or interactions between Lipitor and physical activities such as yoga.
