When you exercise your body uses two different kinds of energy systems, aerobic and anaerobic. During intense exercise such as lifting weights, short sprints and power activities you primarily use the anaerobic system, which requires no oxygen, but does require certain micronutrient elements including creatine. When you access your aerobic system, primarily during activities of longer duration and lower intensity, you use oxygen and carbohydrates as a primary source of energy. Black Widow Performance products contain specialised natural, highly absorbable, instantised micronutrient ingredients that help support these energy systems and their functions. This means that you maximise your performance and exercise potential.
