In this series, we’ve learned creatine definitely increases strength and muscle mass. It accomplishes both by increasing the availability of ATP in muscle tissue, allowing you to workout at a higher intensity. This leads to both strength and size gains. If creatine increases workout intensity and promotes increases in muscle mass, it should also work to decrease body fat.
There are fundamental problems with supplementing creatine in order to improve aerobic performance. While creatine definitely helps improve anaerobic performance, there is much less evidence to suggest it does the same in an aerobic environment.
