After analyzing the sources provided, there is no evidence to suggest that Lipitor (atorvastatin) improves yoga performance. Lipitor is a medication used to lower cholesterol levels in the blood and prevent heart disease [1]. The medication does not appear to have any direct effect on physical performance or yoga practice.

The study cited in the third source [3] investigates the effects of yoga on cardiovascular disease risk factors, such as high blood pressure and cholesterol levels. The study does not mention Lipitor or any other medications, and the focus is on the benefits of yoga practice.

The second source [2] discusses a study on the effects of yoga on cardiovascular health in patients with metabolic syndrome. Again, there is no mention of Lipitor or any other medication affecting yoga performance.

In conclusion, there is no scientific evidence to suggest that Lipitor improves yoga performance. While Lipitor may be helpful in managing cholesterol levels and reducing the risk of heart disease, it does not have a direct impact on physical performance or yoga practice.
