Based on the information provided, there is no direct evidence that Lipitor, a medication used to treat high cholesterol, alters exercise intensity.

According to the first source, Lipitor is a statin medication that works by blocking a substance your body needs to make cholesterol [1]. The second source is a study that discusses the effects of exercise on lipid profile and inflammatory markers in patients with type 2 diabetes mellitus. The study does not mention any correlation between Lipitor and exercise intensity [2]. The third source is an article that discusses the role of statins in the management of hypercholesterolemia, but it does not mention any impact on exercise intensity [3].

However, it is important to note that all medications can have side effects, and some may impact a person's energy levels or physical abilities. If you are taking Lipitor or any other medication and have concerns about your exercise routine, it is best to consult with your healthcare provider.
